VLAI?
Summary
Git LFS permits exfiltration of credentials via crafted HTTP URLs
Details

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.
