Unauthenticated code execution via callable placeholder overwrite
Published Aug 1, 2026 · Updated Aug 1, 2026
Code injection in WPChill Kali Forms 2.4.20 and earlier allows remote attackers to execute arbitrary code through a crafted form submission. The _save_data function lets a submitted thisPermalink value replace a trusted callable placeholder, then passes the attacker-controlled string to call_user_func(). Exploitation requires a target form whose field_type_map contains thisPermalink, entryCounter, or submission_link; successful execution runs with the WordPress server process's privileges.
