Security advisories

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.

The AI SEO/GEO Analyzer module generates SEO/GEO analysis reports by sending content of an entity (including its comments) to an LLM, then converts the model's Markdown response to HTML and stores it for display to privileged users.

The generated HTML was rendered without passing through Drupal's filtering pipeline, so it relied on the LLM output being safe. Under certain circumstances a crafted prompt injection — planted in content that is included in the analysis — can cause the LLM to emit markup that results in stored Cross-site Scripting when the report is later viewed.

This module enables you to use Single Directory Components in site building (views, field formatters, blocks, layouts) and it improves the Developer Experience (DX) with SDC.

The module doesn't sufficiently sanitize the markup passed to components under certain scenarios.

This vulnerability is mitigated by the fact that an attacker must be able to create or update content rendered by UI Patterns.

The Events, Conditions, Actions (ECA) module's Render submodule enables you to build render arrays and render inline Twig templates as part of no-code ECA models.

The module doesn't sufficiently sanitize template code when rendering, which can lead to information disclosure.

This vulnerability is mitigated by the fact that a site must be running an ECA model that uses the "Render: Twig" action on a data flow.

The module doesn't sufficiently sanitize the Siteimprove Analytics identification code when inserting the JavaScript tracking code; this could be exploited to achieve Cross-Site Scripting (XSS).

This vulnerability is mitigated by the fact that an attacker must have a role with the permission "administer siteimprove_analytics".
