Vendor and ecosystem advisories describing this.

WID-SEC-W-2026-3041Drupal Extensions: Mehrere SchwachstellenDeutsch2026-08-26csaf · cert_bundDE
Ein Angreifer kann mehrere Schwachstellen in verschiedenen Drupal Erweiterungen ausnutzen, um Sicherheitsmaßnahmen zu umgehen, sensible Informationen offenzulegen, Daten zu manipulieren und Cross-Site-Scripting-Angriffe durchzuführen.
DRUPAL-CONTRIB-2026-1112026-08-26vendor · osvUS
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.
