Drupal Erweiterungen: Mehrere Schwachstellen
WID-SEC-2026-3284 · first 10.09.2026 · updated 22.10.2026 · CVSS 9,1
What it is about
Drupal ist ein freies Content-Management-System, basierend auf der Scriptsprache PHP und einer SQL-Datenbank. Über zahlreiche Extensions kann der Funktionsumfang der Core-Installation individuell erweitert werden. Ein Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um Datenbankinhalte zu manipulieren oder auszulesen, Zugriffsbeschränkungen und Authentifizierungsmechanismen zu umgehen, vertrauliche Informationen offenzulegen, Cross Site Scripting Angriffe auszuführen, Benutzer auf manipulierte Webseiten umzuleiten, SAML-Authentifizierungen zu beeinflussen oder wiederzuverwenden, interne Ressourcen über SSRF anzusprechen sowie unberechtigt Dateien auf den Server hochzuladen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
