CVE-2026-50024 GitHacker: Path traversal in ref/hash parsing enables existence oracle and hex-fragment exfiltration via a malicious .git server

GitHacker is a tool that restores Git repositories from exposed .git directories. In 1.1.7 and earlier, addheadfiletasks parses an attacker-controlled ref path from .git/HEAD and joins unvalidated path segments onto tempdst/.git/logs/, allowing a malicious server to make GitHacker read an arbitra...

PYSEC-2026-3835 GitHacker: Path traversal in ref/hash parsing enables existence oracle and hex-fragment exfiltration via malicious .git server

Summary GitHacker through 1.1.7 did not validate path segments parsed from attacker-controlled .git/HEAD before joining them onto its output directory. A malicious server could coerce GitHacker into reading arbitrary local files. Contents do not stream back wholesale, but the recovery loop turns...
