TYPO3 Extensions: Mehrere Schwachstellen
WID-SEC-2026-3003 · first 26.08.2026 · updated 26.08.2026 · CVSS 10,0
What it is about
TYPO3 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 verschiedenen TYPO3 Extensions ausnutzen, um beliebigen Programmcode auszuführen, SQL-Injection durchzuführen, erweiterte Berechtigungen zu erlangen, Daten zu manipulieren, sensible Informationen offenzulegen, Sicherheitsmaßnahmen zu umgehen oder einen Denial-of-Service-Zustand auszulösen.
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
- beliebigen Programmcode auszuführen
- SQL-Injection durchzuführen
- erweiterte Berechtigungen zu erlangen
- Daten zu manipulieren
- sensible Informationen offenzulegen
- Sicherheitsmaßnahmen zu umgehen oder einen Denial-of-Service-Zustand auszulösen
