Arbitrary code execution via forged post update
Published Feb 2, 2024 · Updated Jun 20, 2025
CSRF in flusity-CMS 2.33 allows remote attackers to execute arbitrary code through a forged update_post.php request. The proof of concept auto-submits a cross-origin multipart POST that edits an existing post's title, content, status, and role without a CSRF token. Exploitation requires an authenticated administrator to load attacker-controlled content; the public proof of concept demonstrates post modification but does not show the code-execution step.
