CVE-2025-67944Public exploitNetwork attack vector

Editor-level PHP execution via generic capability check

Published Jan 22, 2026 · Updated Jan 22, 2026

Code injection in Nelio Software Nelio A/B Testing 8.1.8 and earlier allows remote authenticated users to execute PHP code on the server. The can_be_edited method checks the generic edit_nab_experiments capability instead of the PHP-specific capability, exposing PHP experiment editing and duplication to Editors. Editor-level access is required, and injected PHP runs with the web server's privileges.
