CVE-2026-46390Public exploitNetwork attack vector

Unauthenticated repository disclosure via user ID substitution

Published Jun 5, 2026 · Updated Jun 5, 2026

Authorization bypass in HAXTheWeb HAXcms (PHP) 2.0.0 through 25.0.0 allows remote attackers to read Git repositories and commit history. The unauthenticated //gitlist/ endpoint indexes repositories by site-owner username and accepts a substituted user ID without checking access. Knowledge of a site owner's user ID and network reachability are sufficient to expose current source and historical commits, including secrets retained in history.
