Vendor and ecosystem advisories describing this.

WID-SEC-W-2026-3168Drupal Erweiterungen: Mehrere SchwachstellenDeutsch2026-09-02csaf · cert_bundDE
Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in verschiedenen Drupal Erweiterungen ausnutzen, um Zugriffsbeschränkungen zu umgehen, geschützte oder sensible Inhalte offenzulegen, Benutzerkonten zu übernehmen, unberechtigte Änderungen oder Löschungen vorzunehmen, Zahlungsstatus zu manipulieren sowie Cross-Site-Scripting-Angriffe auszuführen.
DRUPAL-CONTRIB-2026-1192026-09-02vendor · osvUS
This AI Chatbot module enables you to have a Chatbot using assistants to help you with your Drupal website. The module doesn't sufficiently sanitize for cross site scripting (XSS) when using the structured results using legacy agent setups. This vulnerability is mitigated by the fact that an attacker must be able to invoke a prompt injection set via editorial content and the site must have been setup using AI 1.0.x and AI Agents 1.0.x branch using a uncommon configuration. Any configuration setup or updated after these minor versions are not affected.
