Description OSIDB Bzimport 2026-09-15 15:52:18 UTC 
gitoxide gix-transport before 0.59.2 fails to filter control characters in git-daemon connect requests, allowing attackers to inject NUL/CR/LF bytes via crafted git URLs. Attackers can inject extra NUL-delimited protocol fields to spoof virtual hosts or inject newlines into daemon requests and logs.
