Die Korrekturversionen der Collaborative Development Platform Forgejo 16.0.4 und 15.0.8 wurden ver\u00f6ffentlicht, in denen eine kritische Sicherheitsanf\u00e4lligkeit (CVE nicht zugewiesen) behoben wurde, die es einem Angreifer aus der Ferne erm\u00f6glicht, Code auf dem Server auszuf\u00fchren. Serveradministratoren von Forgejo wird dringend empfohlen, ihre Systeme dringend zu aktualisieren und sicherzustellen, dass keine Anzeichen einer Kompromittierung vorliegen. Die Sicherheitsanf\u00e4lligkeit resultiert aus unzureichender Bereinigung bei der Erstellung eines neuen Repositories aus einer Vorlage. <\/p>\n

Um die Einf\u00fcgung eigener Befehle bei der Verarbeitung der vom Benutzer \u00fcbergebenen Vorlage zu verhindern, entfernt die Plattform das Unterverzeichnis .git\/ vor der Initialisierung eines neuen git-Repositories auf Server<\/a>. Ein Angreifer konnte dieses L\u00f6schen umgehen und ein Unterverzeichnis .git\/ mit seinem Inhalt durch Manipulation von Variablen in Dateien, die im Verzeichnis .forgejo\/template gespeichert waren, erstellen (zum Beispiel durch Ersetzung von \u00ab..\/....\/.git\/hooks\u00bb im Dateipfad). Bei der anschlie\u00dfenden Initialisierung des Git-Repositories verwendete Git die Einstellungen aus dem Unterverzeichnis .git\/, die m\u00f6glicherweise Operationen umfassten, die beliebige Prozesse ausl\u00f6sten. Das Problem wurde gel\u00f6st, indem das Unterverzeichnis .git\/ nicht vor der Aufl\u00f6sung der Variablen, sondern direkt vor dem Ausf\u00fchren von \u00abgit init\u00bb gel\u00f6scht wurde. <\/p>\n

In Gitea 1.25.5 wurde im Februar eine \u00e4hnliche Sicherheitsanf\u00e4lligkeit (CVE-2026-25718) behoben.
