Des versions correctives de la plateforme de d\u00e9veloppement collaboratif Forgejo 16.0.4 et 15.0.8 ont \u00e9t\u00e9 publi\u00e9es, corrigeant une vuln\u00e9rabilit\u00e9 critique (CVE non attribu\u00e9) qui permet \u00e0 un attaquant distant d'ex\u00e9cuter son code sur le serveur. Il est recommand\u00e9 aux administrateurs des serveurs Forgejo de mettre \u00e0 jour leurs syst\u00e8mes imm\u00e9diatement et de s'assurer qu'il n'y a pas de traces de compromission. La vuln\u00e9rabilit\u00e9 est due \u00e0 un manque de nettoyage appropri\u00e9 lors de la cr\u00e9ation d'un nouveau r\u00e9f\u00e9rentiel \u00e0 partir d'un mod\u00e8le. <\/p>\n

Pour pr\u00e9venir l'injection de ses propres commandes lors du traitement d'un mod\u00e8le transmis par l'utilisateur, la plateforme retire le sous-r\u00e9pertoire .git\/ avant d'initialiser un nouveau r\u00e9f\u00e9rentiel git sur le serveur<\/a>. Un attaquant pouvait contourner cette suppression et cr\u00e9er un sous-r\u00e9pertoire .git\/ avec son contenu en manipulant les substitutions de variables dans les fichiers situ\u00e9s dans le r\u00e9pertoire .forgejo\/template (par exemple, en rempla\u00e7ant \u00ab ..\u200b\u200b\/..\u200b\u200b\/.git\/hooks \u00bb dans le chemin de fichier). Lors de l'initialisation ult\u00e9rieure du d\u00e9p\u00f4t git, Git appliquait les param\u00e8tres du sous-r\u00e9pertoire .git\/, qui pouvaient inclure des op\u00e9rations lan\u00e7ant des processus arbitraires. Le probl\u00e8me a \u00e9t\u00e9 r\u00e9solu en supprimant le sous-r\u00e9pertoire .git\/ non pas avant de r\u00e9v\u00e9ler les variables, mais juste avant d'ex\u00e9cuter \u00ab git init \u00bb. <\/p>\n

Dans Gitea 1.25.5, une vuln\u00e9rabilit\u00e9 similaire (CVE-2026-25718) a \u00e9t\u00e9 corrig\u00e9e en f\u00e9vrier.
