CVE-2025-58158Network attack vector

Arbitrary file write via unchecked LFS object ID

Published Aug 29, 2025 · Updated Aug 29, 2025

Path traversal in Harness Open Source Gitness before 3.3.0 allows remote authenticated users to write files outside LFS storage. The Upload controller passes a client-supplied LFS object ID into getLFSObjectPath and writes the request body without verifying that its SHA-256 hash matches the ID. Git LFS must be in use and the attacker must have API access; a crafted upload can replace any file writable by the service account and compromise the server.
