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...

CVE-2026-87817

A flaw was found in GitPython. This vulnerability allows a remote attacker to execute arbitrary code. By failing to properly validate the git directory location, GitPython allows attackers to impersonate the git directory using tracked files such as gitdir, commondir, and HEAD. An attacker can th...
