Vendor and ecosystem advisories describing this.

WID-SEC-W-2026-2181Drupal Extensions: Mehrere SchwachstellenDeutsch2026-07-01csaf · cert_bundDE
Ein entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um einen Cross-Site Scripting Angriff durchzuführen, Sicherheitsmaßnahmen zu umgehen und Daten zu manipulieren.
DRUPAL-CONTRIB-2026-0682026-07-01vendor · osvUS
This module enables you to test and run AI-driven workflows interactively through a chat interface. The module doesn't sufficiently re-evaluate a human-in-the-loop approval gate where the workflow iterates more than once. This may result in execution of workflows that were not intended by the user. This vulnerability is mitigated by the fact that an attacker must have a role with the permission "Administer FlowDrop workflows" (or the equivalent "Create FlowDrop workflows" / "Edit FlowDrop workflows" permissions).
