CVE-2026-82668Public exploitNetwork attack vectorHinoki check available

Remote code execution via trusted textconv helpers

Published Aug 31, 2026 · Updated Aug 31, 2026

OS command injection in Klaus Silveira GitList 2.0.0 allows remote attackers to execute code as the web service user via crafted repositories. CommandLine.php globally sets safe.directory to an unrestricted value, after which commit and blame rendering invoke Git without disabling repository-controlled textconv helpers. Exploitation requires an attacker-controlled, foreign-owned repository in a scanned directory and HTTP requests that first establish trust and then render its content.
