WID-SEC-W-2026-2826Drupal Module: Mehrere SchwachstellenDeutsch2026-08-12csaf · cert_bundDE
Ein Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um Informationen offenzulegen, Daten zu manipulieren und Sicherheitsmaßnahmen zu umgehen.
DRUPAL-CONTRIB-2026-0962026-08-12vendor · osvUS
This module enables you to view the differences between revisions on any entity type. The module doesn't sufficiently restrict access to non-node entity revision diffs. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to view the entity.
