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.

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 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.
