| Doc Text: |
A flaw was found in gix-transport. This vulnerability allows a remote attacker to inject control characters, specifically NUL, Carriage Return (CR), and Line Feed (LF) bytes, into git-daemon connect requests by crafting malicious git URLs. This injection can lead to spoofing of virtual hosts or the insertion of newlines into daemon requests and logs, potentially causing information disclosure or unexpected behavior.
