CVE-2026-12697Public exploitNetwork attack vector

Cross-user AI chat history deletion via unchecked ownership

Published Jul 31, 2026 · Updated Jul 31, 2026

IDOR in gVectors Team wpForo Forum before 3.1.2 allows remote authenticated users to permanently delete other users' stored AI chat messages. The wpforo_ai_chat_delete_conversation AJAX action accepts an enumerable conversation_id and deletes its message rows without checking conversation ownership. The endpoint is enabled by default; subscriber-level access and a valid nonce are required, and the flaw does not expose message contents.
