Published

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.

Affected versions, risk and source history

Exploitation and risk

Source status

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

Risk history

Compare earlier KEV listings and daily EPSS scores. Advisory wording and affected versions have a separate history.

When does an EPSS score appear as a change?

A prediction change is reported when EPSS rises from below 10% to 10% or higher. Other daily score changes remain in this history.

Advisory history

1 saved versions

See how the publisher's advisory changed over time. Each link opens the version saved at that time. The publisher's update date can differ from the date shown here.

How advisory history works

Each link identifies one complete publisher record. History can include advisories that previously shared an identifier; an identifier removed by a publisher no longer establishes a current relationship. A historical link shows only that record and earlier saved versions. Failed checks and unchanged reads do not create new versions.
