Security advisories

This module enables you to disable access to the /user/login form unless a secret key is provided.

The module does not invalidate the relevant caches when login page access restrictions are enabled. As a result, previously cached login page responses may remain accessible until caches are cleared. An attacker may continue to access the login page despite the restriction having been enabled.

The Digital Signage Framework module provides a route that signage devices can call to refresh dynamic blocks on a display.

The route did not check whether the requester was a signage device, nor whether the requested block was one that the module delivers to displays. As a result, an anonymous visitor could read the rendered content of blocks they were not meant to see.

This vulnerability is mitigated by the fact that many block plugins perform their own access checks on the content they display, which limits what can be disclosed through this route.

The module provides a permission that allows users to configure email templates containing Twig code. This permission was not marked as restricted.

A site administrator might inadvertently grant this permission to less-trusted users. This would allow those users to execute Twig within email templates, and to gain access to functionality and information intended only for highly trusted administrators.

This module enables site administrators to require CAPTCHA confirmation on specific pages.

The module does not sufficiently validate its CAPTCHA verification cookies. Under certain circumstances, an unauthenticated user or automated bot can forge the cookie and bypass CAPTCHA verification entirely.
