Drupal core - Moderately critical - Third-party libraries - SA-CORE-2026-013

Drupal Security Team — Wed, 16 Sep 2026 16:21:04 +0000

Project:

Drupal core

Project machine name:

drupal

Date:

2026-September-16

Security risk:

Moderately critical 13 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default

Vulnerability:

Third-party libraries

Affected versions:

>=10.5.0 <10.6.17 || >=11.0.0 <11.3.17 || >=11.4.0 <11.4.7

Description:

The Drupal project uses the CKEditor library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal.

Vulnerabilities are possible if Drupal is configured to use CKEditor for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit this Cross-Site Scripting (XSS) vulnerability to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

For more information, see CKEditor's security advisory:

High-severity Cross-site scripting (XSS) in the engine package

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.4.x, update to Drupal 11.4.7.
If you use Drupal 11.3.x, update to Drupal 11.3.17.
Drupal 11.2.x and below are end-of-life and do not receive security coverage.

Drupal 10

If you use Drupal 10.6.x, update to Drupal 10.6.17.
Drupal 10.5.x and below are end-of-life and do not receive security coverage.

Note that Drupal 8 and Drupal 9 have both reached end-of-life.

Instructions for contributed modules

Site owners should also review their site following the protocol for managing external libraries and plugins, as contributed projects may use additional CKEditor plugins not packaged in Drupal core.

CKEditor has also released another CVE in today's release that does not affect Drupal, but may affect custom plugins or other usecases:

Vulnerability:

Cross-site scripting

Affected versions:

>=11.3.0 <11.3.14 || >=11.4.0 <11.4.4 || 11.2.*

CVE IDs:

CVE-2026-15917

Description:

Drupal core 11.2 and above integrate the HTMX JavaScript library.

Drupal core's XSS filter does not sufficiently sanitize certain HTMX attributes, which can lead to a cross-site scripting (XSS) vulnerability.

The vulnerability is mitigated by the fact an attacker must be able to insert HTML with specific attributes.

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.4.x, update to Drupal 11.4.4.
If you use Drupal 11.3.x, update to Drupal 11.3.14.

Security risk:

Moderately critical 10 ∕ 25 AC:Complex/A:None/CI:Some/II:None/E:Theoretical/TD:Uncommon

Vulnerability:

Information disclosure

Affected versions:

<10.6.13 || >=11.3.0 <11.3.14 || >=11.4.0 <11.4.4 || 11.0.* || 11.1.* || 11.2.*

CVE IDs:

CVE-2026-15916

Description:

The Image module allows you to define and configure image fields.

The module doesn't sufficiently check access to image style derivatives when those files are served via a file stream other than private://.

This vulnerability is mitigated by the fact that Drupal must be configured to use a contributed (non-core) file scheme to serve private derived images.

Information disclosure issues like this one are not generally given security advisories (as described in PSA-2023-07-12)). This fix is provided as a hardening. Contributed modules implementing custom stream wrappers may need to add similar hardenings.

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.4.x, update to Drupal 11.4.4.
If you use Drupal 11.3.x, update to Drupal 11.3.14.

CVE IDs:

CVE-2026-55808

Description:

The JSON:API and REST modules allow you to upload image files to image fields.

The validation rules check the file extension of the uploaded file but not the file MIME type. This may allow a malicious user to upload a file that is not an image.

Certain web-server configurations may serve the uploaded file with its actual MIME type rather than an image type. This may lead to cross-site scripting (XSS) or other unexpected behavior.

Solution:

Drupal core

Project machine name:

drupal

Date:

2026-June-17

Security risk:

Moderately critical 10 ∕ 25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:Default

Vulnerability:

Server-side request forgery

Affected versions:

CVE IDs:

CVE-2026-55807

Description:

The Media module comes with support for oEmbed. The oEmbed specification contains two discovery mechanisms, via providers.json and via URL discovery.

The URL discovery code could be leveraged to trick Drupal into making server-side requests to any URL.

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.3.x, update to Drupal 11.3.12.
If you use Drupal 11.2.x, update to Drupal 11.2.14.

Drupal 10

If you use Drupal 10.6.x, update to Drupal 10.6.11.
If you use Drupal 10.5.x, update to Drupal 10.5.12.

Drupal 11.1.x, Drupal 11.0.x, Drupal 10.4.x, and below are end-of-life and do not receive security coverage. (Drupal 8 and Drupal 9 have both reached end-of-life.)

Required site changes for URL discovery

Most users of the oEmbed functionality in Drupal likely use providers.json to define known providers (such as YouTube and Vimeo) for embedding content.

If you are using URL discovery, you now need to set a list of trusted oEmbed discovery hosts in settings.php.

This is an array containing a series of regular expressions for matching host names for discovery. It follows the same pattern as the existing trusted hosts settings.

Example:

// Only allow URL discovery from example.com.
$settings['media_oembed_discovery_trusted_host_patterns'] = [
  '^example\.com$',
];

CVE IDs:

CVE-2026-55804

Description:

Drupal core contains a chain of methods that could be exploitable when an insecure deserialization vulnerability exists on the site. This so-called "gadget chain" presents no direct threat, but is a vector that can be used to achieve remote code execution or SQL injection if the application deserializes untrusted data due to another vulnerability.

This issue is not directly exploitable.

This issue is mitigated by the fact that in order for it to be exploitable, a separate vulnerability must be present to allow an attacker to pass unsafe input to unserialize().

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.3.x, update to Drupal 11.3.12.
If you use Drupal 11.2.x, update to Drupal 11.2.14.

Drupal core - Critical - PHP object injection - SA-CORE-2026-005

Date:

2026-June-17

Security risk:

Critical 18 ∕ 25 AC:None/A:User/CI:All/II:All/E:Theoretical/TD:Uncommon

Vulnerability:

PHP object injection

Affected versions:

<10.5.12 || >=10.6.0 <10.6.11 || >=11.2.0 <11.2.14 || >=11.3.0 <11.3.12 || 11.0.* || 11.1.*

CVE IDs:

CVE-2026-55803

Description:

SA-CORE-2019-003 added protection for fields that store serialized data to disallow direct writes via web services.

The above fix did not cover all potential attack vectors for JSON:API. An attacker with appropriate JSON:API write permission could potentially inject a malicious payload in certain rare circumstances, potentially resulting in PHP Object Injection.

This vulnerability is mitigated by the fact that in order to be exploitable:

A site must use an entity reference field type that stores a serialized property.
An attacker must have permission to write to the entity via JSON:API.

No field type shipped with Drupal core meets these criteria, and contributed or user-created field types that do appear to be extremely unusual. This update protects all such fields; no changes are required in contributed modules.

JSON:API is read-only by default, so sites are only affected if they have enabled write access (either through administrator configuration or the installation of a contributed or custom module that enables write access).

Drupal Steward protection:

This issue is being protected by Drupal Steward. In this instance, we believe that the WAF rule will provide mitigation for the common/obvious vulnerability paths, but may not cover all cases or work for all hosting providers. Additionally, several other core security advisories released today are not mitigated by Drupal Steward. Therefore, our recommended action is still to plan an actual Drupal update within 24 hours of this release.

Solution:

Install the latest version:

Drupal 11

If you use Drupal 11.3.x, update to Drupal 11.3.12.
If you use Drupal 11.2.x, update to Drupal 11.2.14.

Date:

2026-May-20

Security risk:

Highly critical 23 ∕ 25 AC:None/A:None/CI:All/II:All/E:Exploit/TD:Uncommon

Vulnerability:

SQL injection

Affected versions:

>= 8.9.0 < 10.4.10 || >= 10.5.0 < 10.5.10 || >= 10.6.0 < 10.6.9 || >= 11.0.0 < 11.1.10 || >= 11.2.0 < 11.2.12 || >= 11.3.0 < 11.3.10

CVE IDs:

CVE-2026-9082

Description:

Drupal core includes a database abstraction API to ensure that queries executed against the database are sanitized to prevent SQL injection attacks.

A vulnerability in this API allows an attacker to send specially crafted requests, resulting in arbitrary SQL injection for sites using PostgreSQL databases. This can lead to information disclosure, and in some cases privilege escalation, remote code execution, or other attacks.

This vulnerability can be exploited by anonymous users.

This SQL injection vulnerability only affects sites using PostgreSQL. However, the third-party dependency updates in these releases apply to all sites.

Updates

May 22 2026, 04:30 UTC: The risk score has been updated to reflect that exploit attempts are now being detected in the wild.

Upstream security advisories

The Drupal releases for supported branches (11.3, 11.2, 10.6, and 10.5) in this advisory also include security updates for Symfony and Twig. Those projects have released important Security Advisories that were coordinated with this Drupal release, and Drupal is affected by some of the vulnerabilities.

Depending on your site configuration and contrib modules, you may be vulnerable to one or more of these upstream issues, so updating these dependencies is highly recommended whether the SQL Injection vulnerability affects you or not. It is also recommended to review which user roles have the ability to update Twig templates, for example via Views or contributed modules.

Solution:

Install the latest version.

Drupal 11

If you use Drupal 11.3.x, update to Drupal 11.3.10.

CVE IDs:

CVE-2025-13083

Description:

The core system module handles downloads of private and temporary files. Contrib modules can define additional kinds of files (schemes) that may also be handled by the system module.

In some cases, files may be served with the HTTP header Cache-Control: public when they should be uncacheable. This can lead to some users getting cached versions of files with information they should not be able to access. For example, files may be cached by Varnish or a CDN.

This vulnerability is mitigated by the following:

Drupal must be configured to handle non-public files using a custom or contributed module providing an additional file scheme.
An attacker must know to request a file that has previously been
requested by a more-privileged user, and that file must still be cached.

Solution:

Install the latest version:

If you are using Drupal 10.4, update to Drupal 10.4.9.
If you are using Drupal 10.5, update to Drupal 10.5.6.
If you are using Drupal 11.1, update to Drupal 11.1.9.

CVE IDs:

CVE-2025-13080

Description:

Drupal Core has a rarely used feature, provided by an underlying library, which allows certain attributes of incoming HTTP requests to be overridden.

This functionality can be abused in a way that may cause Drupal to cache response data that it should not. This can lead to legitimate requests receiving inappropriate cached responses (cache poisoning).

This could be exploited in various ways:

Broken rendering of some pages
Unstyled or malformatted pages
Adverse impacts on client-side functionality

Changes are being made in the underlying library which will mitigate this problem, but in the meantime Drupal core has been hardened to protect against this vulnerability. The authors of the underlying library do not believe it is a source of vulnerabilities in other systems. Drupal's use of library leads to an implementation-specific vulnerability, so we've issued this advisory and reserved a CVE ID for the vulnerability in Drupal.

Solution:

Install the latest version:

If you are using Drupal 10.4, update to Drupal 10.4.9.
If you are using Drupal 10.5, update to Drupal 10.5.6.
If you are using Drupal 11.1, update to Drupal 11.1.9.

CVE IDs:

CVE-2025-31675

Description:

Drupal core Link field attributes are not sufficiently sanitized, which can lead to a Cross Site Scripting vulnerability (XSS).

This vulnerability is mitigated by that fact that an attacker would need to have the ability to add specific attributes to a Link field, which typically requires edit access via core web services, or a contrib or custom module.

Sites with the Link module disabled or that do not use any link fields are not affected.

Solution:

Install the latest version:

CVE IDs:

CVE-2025-31673

Description:

Bulk operations allow authorized users to modify several nodes at once from the Content page (/admin/content). A site builder can also add bulk operations to other pages using Views.

A bug in the core Actions system allows some users to modify some fields using bulk actions that they do not have permission to modify on individual nodes.

This vulnerability is mitigated by the fact that an attacker must have permission to access /admin/content or other, custom views and to edit nodes.

In particular, the bulk operations

Make content sticky
Make content unsticky
Promote content to front page
Publish content
Remove content from front page
Unpublish content

now require the "Administer content" permission.

Solution:

>=8.7.0 <9.5.11 || >=10.0 <10.0.11 || >= 10.1 <10.1.4

CVE IDs:

CVE-2023-5256

Description:

In certain scenarios, Drupal's JSON:API module will output error backtraces. With some configurations, this may cause sensitive information to be cached and made available to anonymous users, leading to privilege escalation.

This vulnerability only affects sites with the JSON:API module enabled, and can be mitigated by uninstalling JSON:API.

The core REST and contributed GraphQL modules are not affected.

Drupal Steward partners have been made aware of this issue. Some platforms may provide mitigations. However, not all WAF configurations can mitigate the issue, so it is still recommended to update promptly to this security release if your site uses JSON:API.

Solution:

Install the latest version:

If you are using Drupal 10.1, update to Drupal 10.1.4.
If you are using Drupal 10.0, update to Drupal 10.0.11.
If you are using Drupal 9.5, update to Drupal 9.5.11.

Vulnerability:

Multiple vulnerabilities

Affected versions:

>= 8.0.0 <9.3.22 || >= 9.4.0 <9.4.7

CVE IDs:

CVE-2022-39261

Description:

Drupal uses the Twig third-party library for content templating and sanitization. Twig has released a security update that affects Drupal. Twig has rated the vulnerability as high severity.

Drupal core's code extending Twig has also been updated to mitigate a related vulnerability.

Multiple vulnerabilities are possible if an untrusted user has access to write Twig code, including potential unauthorized read access to private files, the contents of other files on the server, or database credentials.

The vulnerability is mitigated by the fact that an exploit is only possible in Drupal core with a restricted access administrative permission. Additional exploit paths for the same vulnerability may exist with contributed or custom code that allows users to write Twig templates.

Solution:

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.7.
If you are using Drupal 9.3, update to Drupal 9.3.22.

All versions of Drupal 9 prior to 9.3.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

2022-July-20

Security risk:

Critical 15 ∕ 25 AC:Basic/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon

Vulnerability:

Arbitrary PHP code execution

Affected versions:

>= 8.0.0 <9.3.19 || >= 9.4.0 <9.4.3

CVE IDs:

CVE-2022-25277

Description:

Updated 2022-07-20 19:45 UTC to indicate that this only affects Apache web servers.

Drupal core sanitizes filenames with dangerous extensions upon upload (reference: SA-CORE-2020-012) and strips leading and trailing dots from filenames to prevent uploading server configuration files (reference: SA-CORE-2019-010).

However, the protections for these two vulnerabilities previously did not work correctly together. As a result, if the site were configured to allow the upload of files with an htaccess extension, these files' filenames would not be properly sanitized. This could allow bypassing the protections provided by Drupal core's default .htaccess files and possible remote code execution on Apache web servers.

This issue is mitigated by the fact that it requires a field administrator to explicitly configure a file field to allow htaccess as an extension (a restricted permission), or a contributed module or custom code that overrides allowed file uploads.

Solution:

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.3.
If you are using Drupal 9.3, update to Drupal 9.3.19.

All versions of Drupal 9 prior to 9.3.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 core is not affected.

Auditing your files directory's `.htaccess` to ensure it has not been overwritten or overridden in a subdirectory

If your web server uses Apache httpd with AllowOverride, you should check within your files directories and subdirectories to ensure that any .htaccess files present are intentional. You can search for files named .htaccess by running the following command in the roots of both your public and private files directory:

find ./ -name ".htaccess" -print

Drupal automatically creates .htaccess files like the following in the root of the public files directory:

# Turn off all options we don't need.
Options -Indexes -ExecCGI -Includes -MultiViews

# Set the catch-all handler to prevent scripts from being executed.
SetHandler Drupal_Security_Do_Not_Remove_See_SA_2006_006
<Files *>
  # Override the handler again if we're run later in the evaluation list.
  SetHandler Drupal_Security_Do_Not_Remove_See_SA_2013_003
</Files>

# If we know how to do it safely, disable the PHP engine entirely.
<IfModule mod_php7.c>
  php_flag engine off
</IfModule>
<IfModule mod_php.c>

Vulnerability:

Access Bypass

Affected versions:

>= 8.0.0 <9.3.19 || >= 9.4.0 <9.4.3

CVE IDs:

CVE-2022-25278

Description:

Under certain circumstances, the Drupal core form API evaluates form element access incorrectly. This may lead to a user being able to alter data they should not have access to.

No forms provided by Drupal core are known to be vulnerable. However, forms added through contributed or custom modules or themes may be affected.

This advisory is not covered by Drupal Steward.

Solution:

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.3.
If you are using Drupal 9.3, update to Drupal 9.3.19.

All versions of Drupal 9 prior to 9.3.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Vulnerability:

Information Disclosure

Affected versions:

>=7.0 <7.91 || >= 8.0.0 <9.3.19 || >= 9.4.0 <9.4.3

CVE IDs:

CVE-2022-25275

Description:

In some situations, the Image module does not correctly check access to image files not stored in the standard public files directory when generating derivative images using the image styles system.

Access to a non-public file is checked only if it is stored in the "private" file system. However, some contributed modules provide additional file systems, or schemes, which may lead to this vulnerability.

This vulnerability is mitigated by the fact that it only applies when the site sets (Drupal 9) $config['image.settings']['allow_insecure_derivatives'] or (Drupal 7) $conf['image_allow_insecure_derivatives'] to TRUE. The recommended and default setting is FALSE, and Drupal core does not provide a way to change that in the admin UI.

Some sites may require configuration changes following this security release. Review the release notes for your Drupal version if you have issues accessing files or image styles after updating.

Solution:

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.3.
If you are using Drupal 9.3, update to Drupal 9.3.19.
If you are using Drupal 7, update to Drupal 7.91.

CVE-2022-31043

Description:

Updated 22:00 UTC 2022-06-10: Added steps to update without drupal/core-recommended.

Drupal uses the third-party Guzzle library for handling HTTP requests and responses to external services. Guzzle has released two security advisories:

These do not affect Drupal core, but may affect some contributed projects or custom code on Drupal sites.

We are issuing this security advisory outside our regular Drupal security release window schedule since Guzzle has already published information about the vulnerabilities, and vulnerabilities might exist in contributed modules or custom modules that use Guzzle for outgoing requests. Guzzle has rated these vulnerabilities as high-risk.

This advisory is not covered by Drupal Steward.

Solution:

Install the latest version:

If you are using Drupal 9.4, update to Drupal 9.4.0-rc2.
If you are using Drupal 9.3, update to Drupal 9.3.16.
If you are using Drupal 9.2, update to Drupal 9.2.21.

All versions of Drupal 9 prior to 9.2.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Drupal 7 is not affected.

Advanced users may also work around this issue by temporarily using drupal/core instead of drupal/core-recommended and then updating Guzzle to the desired version. More information on managing Guzzle with Drupal 9.4.

Description:

The Drupal project uses the CKEditor library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal.

Vulnerabilities are possible if Drupal is configured to allow use of the CKEditor library for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

For more information, see CKEditor's security advisories:

This advisory is not covered by Drupal Steward.

Solution:

Install the latest version:

If you are using Drupal 9.3, update to Drupal 9.3.8.
If you are using Drupal 9.2, update to Drupal 9.2.15.

All versions of Drupal 9 prior to 9.2.x are end-of-life and do not receive security coverage. Note that Drupal 8 has reached its end of life.

Instructions for Drupal 7 and contributed modules

Drupal 7 core is not affected, although Drupal 7, 8, and 9 site owners should review their site following the protocol for managing external libraries and plugins previously suggested by the Drupal Security Team, as contributed projects may use additional CKEditor plugins not packaged in Drupal core.

Users of the Webform module should ensure Webform's version of CKEditor 4 is also up-to-date after updating Drupal core and libraries for any affected contributed modules. Learn more about updating Webform libraries.

Security risk:

Moderately critical 14 ∕ 25 AC:Basic/A:User/CI:Some/II:Some/E:Proof/TD:Default

Vulnerability:

Cross site scripting

Affected versions:

>7.0 <=7.86

Description:

jQuery UI is a third-party library used by Drupal. This library was previously thought to be end-of-life.

Late in 2021, jQuery UI announced that they would be continuing development, and released a jQuery UI 1.13.0 version. In addition to the issue covered by SA-CORE-2022-001, further security vulnerabilities disclosed in jQuery UI 1.13.0 may affect Drupal 7 only:

CVE-2021-41182: XSS in the altField option of the Datepicker widget
CVE-2021-41183: XSS in *Text options of the Datepicker widget

Furthermore, other vulnerabilities listed below were previously unaddressed in the version of jQuery UI included in Drupal 7 or in the jQuery Update module:

CVE-2016-7103: XSS in closeText option of Dialog
CVE-2010-5312: XSS in the title option of Dialog (applicable only to the jQuery UI version included in D7 core)

It is possible that these vulnerabilities are exploitable via contributed Drupal modules or custom code. As a precaution, this Drupal security release applies the fix for the above cross-site scripting issues, without making other changes to the jQuery UI version that is included in Drupal.

This advisory is not covered by Drupal Steward.

Important note regarding the jQuery Update contrib module

These backport fixes in D7 have also been tested with the version of jQuery UI provided by the most recent releases of the jQuery Update module (jQuery UI 1.10.2) and the fixes confirmed. Therefore, there is no accompanying security release for jQuery Update.

However, in early 2022 the currently supported release of jQuery Update (7.x-2.7 from 2015) will be deprecated and replaced by a new release from the 7.x-4.x branch. The stable release from that branch will then be the only release considered by Drupal Security Team when new jQuery security issues arise.

Please check the jQuery Update project page for more details, and for announcements when the changes are made to supported releases.

Solution:

Install the latest version:

If you are using Drupal 7, update to Drupal 7.86
