CVSS 8.1 · High EPSS 0,19%

Kerentanan Time-of-check Time-of-use (TOCTOU) Race Condition pada gitea. Skor CVSS 3.1 8.1 (High) menurut CISA ADP.

Deskripsi (NVD)

Gitea validated a push mirror's remote address against the `[migrations]` allow and block lists only when the mirror was created. Each synchronization passed the stored address directly to `git push`, so a name that later resolved to a blocked or internal address was still reached. A user with administrator access to a repository, which includes repositories they create themselves, could aim push mirror synchronization at internal Git services and force-push the repository's contents to them.
