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

GitHacker is a tool that restores Git repositories from exposed .git directories. In 1.1.7 and earlier, add_head_file_tasks parses an attacker-controlled ref path from .git/HEAD and joins unvalidated path segments onto temp_dst/.git/logs/, allowing a malicious server to make GitHacker read an arbitrary local file when a victim runs the tool against the server's URL. add_hashes_parsed then scans the file for 40-character hexadecimal substrings and requests each match through .git/objects using the first two characters and remaining characters as path components, creating an attacker-observable existence oracle and disclosing matching hexadecimal fragments. Complete file contents are not returned, and the add_folder and add_task write path in shipped version 1.1.7 does not permit an escape. This issue is fixed in repository version 1.1.9.
