CVE-2024-31666Public exploitNetwork attack vector

Authenticated code execution via unauthorized add-on editing

Published Apr 22, 2024 · Updated Mar 26, 2025

Code injection in Flusity-CMS 2.33 allows remote authenticated users to execute arbitrary code through edit_addon_post.php. The endpoint accepts add-on edit requests from an ordinary account without enforcing its administrator-only authorization boundary. The public proof demonstrates the privilege bypass, while the CVE record asserts arbitrary code execution without disclosing the crafted script or execution path.
