Lack of data validation In git-lfs
Description
Git LFS permits exfiltration of credentials via crafted HTTP URLs
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.
