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.

Fixes

Solution

Upgrade to gittuf 0.18.0 or later, which asks Git for raw paths. Then re-run verification (gittuf verify-ref) for each protected reference: a reference that passed verification before the upgrade but fails after it contains a change that should have been blocked.

Workaround

No workaround given by the vendor.
