The manipulation with an unknown input leads to a improper authorization vulnerability. Using CWE to declare the problem leads to CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Impacted is integrity. The summary by CVE is:

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.

Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1548.002 for this issue.
