MEDIUMCVSS 5.5/10

Last modified

CVE-2026-128034 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In gittuf before 0.18.0, verification of file protection rules uses the quoted, escaped pathnames that Git prints by default for files with special characters (for example non-ASCII characters) instead of the raw paths. Such paths do not match patterns like file:internal/*, so the files are treated as unprotected, and a user who is not authorized by a file protection rule can change a protected file whose name contains special characters and still pass verification..
