Vulnerability details

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insufficient validation of CR/LF characters in URLs. 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 A remote attacker can pass specially crafted URL to the application and obtain credentials.
