FKIE_CVE-2026-70402

Vulnerability from fkie_nvd - Published: 2026-10-14 15:17 - Updated: 2026-10-14 16:17
Severity
5.8 (Medium) - CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:H/A:L
Summary
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.
