Drupal Extensions: Mehrere Schwachstellen
WID-SEC-2026-2181 · first 02.07.2026 · updated 13.07.2026 · CVSS 6,4
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 entfernter, authentisierter Angreifer kann mehrere Schwachstellen in Drupal ausnutzen, um einen Cross-Site Scripting Angriff durchzuführen, Sicherheitsmaßnahmen zu umgehen und Daten zu manipulieren.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- einen Cross-Site Scripting Angriff durchzuführen
- Sicherheitsmaßnahmen zu umgehen
- Daten zu manipulieren
Am I affected?
Affected according to the BSI:
- Open Source Drupal Canvas <1.4.2
- Open Source Drupal Canvas <1.5.2
- Open Source Drupal Canvas <1.6.1
- Open Source Drupal Canvas <1.7.1
- Open Source Drupal FlowDrop <1.6.0
- Open Source Drupal Colorbox <2.1.5
- Open Source Drupal Colorbox <2.2.1
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 Canvas 1.4.2
- Open Source Drupal Canvas 1.5.2
- Open Source Drupal Canvas 1.6.1
- Open Source Drupal Canvas 1.7.1
- Open Source Drupal FlowDrop 1.6.0
- Open Source Drupal Colorbox 2.1.5
- Open Source Drupal Colorbox 2.2.1
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.
