WID-SEC-2026-1533 · first 14.05.2026 · updated 20.05.2026 · CVSS 7,5
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 Informationen offenzulegen, Sicherheitsmaßnahmen zu umgehen, Daten zu manipulieren oder Cross-Site-Scripting-Angriffe durchzuführen.
Under what conditions?
The BSI does not name any particular preconditions. Exploitable remotely according to the BSI.
What can happen in the worst case
An attacker could use the vulnerability to
- Informationen offenzulegen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren oder Cross-Site-Scripting-Angriffe durchzuführen
Am I affected?
Affected according to the BSI:
- Open Source Drupal Colorbox Inline <2.1.1
- Open Source Drupal Date iCal <4.0.15
- Open Source Drupal GTranslate <3.0.5
- Open Source Drupal Node View Permissions <1.7.0
- Open Source Drupal Node View Permissions <2.0.1
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?
Update to at least:
- Open Source Drupal Colorbox Inline 2.1.1
- Open Source Drupal Date iCal 4.0.15
- Open Source Drupal GTranslate 3.0.5
- Open Source Drupal Node View Permissions 1.7.0

Is the vulnerability already being exploited?
None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
