What it is about

GitLab ist eine Webanwendung zur Versionsverwaltung für Softwareprojekte auf Basis von git. Ein Angreifer kann mehrere Schwachstellen in GitLab ausnutzen, um beliebigen Code auszuführen, erweiterte Berechtigungen zu erlangen, Sicherheitsmaßnahmen zu umgehen, sensible Informationen oder Anmeldedaten offenzulegen, Daten zu manipulieren, Cross-Site-Scripting-Angriffe durchzuführen oder Denial-of-Service-Zustände zu verursachen.

Under what conditions?
