Gitea local code execution through writable Git hooks

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Gitea creates server-side Git hook directories and scripts with mode 0777 and relies on the process umask to restrict access. With a permissive umask such as 0000 or 0002, another local user who can reach the repository storage may modify a hook or add an executable to a writable hook directory. A later Git operation can execute that file as the Gitea service account.
