A remote code execution vulnerability exists within the Field UI module in Drupal core. The vulnerability is not directly exploitable with core alone, but multiple serious exploit paths exist with contributed modules. At least one known exploit path does not require authentication. Custom code may also expose the vulnerable functionality. The vulnerability can be mitigated by uninstalling the core Field UI module (fieldui), which will provide protection while sites are updated. Drupal Steward protection: This issue is being protected by Drupal Steward. Sites that use Drupal Steward are already protected from some known attack vectors, but the protection offered will not cover all possible exploits. Sites should upgrade in the near future in case additional attack vectors are discovered.

The Navigation module doesn't sufficiently sanitize certain attributes, which can lead to a cross-site scripting (XSS) vulnerability. This vulnerability is mitigated by the fact that an attacker must have a role with permission to enter HTML tags containing specific data attributes, or the administer menu permission.

The Drupal core Link module provides a field type that can be used for internal and external URLs. The module does not sufficiently sanitize certain markup in some circumstances, which can lead to cross-site scripting (XSS) vulnerabilities.

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:

Incorrect Authorization vulnerability in Drupal Webform REST allows Forceful Browsing. This issue affects Webform REST versions: from 0.0.0 to 4.1.0.

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.

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.

The Layout Builder module doesn't sufficiently sanitize block labels in certain scenarios, which can lead to a cross-site scripting (XSS) vulnerability. This is mitigated by the fact that both the attacker and the targeted user need to be using the Layout Builder editing interface.
