WID-SEC-2026-2665 · first 06.08.2026 · updated 27.08.2026 · CVSS 9,0
What it is about
Jenkins ist ein erweiterbarer, webbasierter Integration Server zur kontinuierlichen Unterstützung bei Softwareentwicklungen aller Art. Ein Angreifer kann mehrere Schwachstellen in Jenkins ausnutzen, um beliebigen Code auszuführen, Berechtigungen zu erweitern, Sicherheitsmaßnahmen zu umgehen, vertrauliche Informationen offenzulegen, Daten zu manipulieren sowie Cross-Site-Scripting- (XSS) oder Server-Side-Request-Forgery- (SSRF) 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
- beliebigen Code auszuführen
- Berechtigungen zu erweitern
- Sicherheitsmaßnahmen zu umgehen
- vertrauliche Informationen offenzulegen
- Daten zu manipulieren sowie Cross-Site-Scripting- (XSS) oder Server-Side-Request-Forgery- (SSRF) Angriffe durchzuführen
