GHSA-q6r2-x2cc-vrp7 Git LFS permits exfiltration of credentials via crafted HTTP URLs

• Go github.com/git-lfs/git-lfs: >= 0.1.0, <= 3.0.0 (no fix yet) • Go github.com/git-lfs/git-lfs/v3: >= 3.0.0, < 3.6.1 → fixed in 3.6.1

Impact When Git LFS requests credentials from Git for a remote host, it passes portions of the host's URL to the `git-credential(1)` command without checking for embedded line-ending control characters, and then sends any credentials it receives back from the Git credential helper to the remote host. By inserting URL-encoded control characters such as line feed (LF) or carriage return (CR) characters into the URL, an attacker may be able to retrieve a user's Git credentials. Patches This problem exists in all previous versions and is patched in v3.6.1. All users should upgrade to v3.6.1. Workarounds There are no workarounds known at this time.
