CVE-2023-50172Public exploitNetwork attack vector

Unauthenticated recovery-code creation via late captcha validation

Published Jan 10, 2024 · Updated Nov 4, 2025

Weak password recovery in WWBN AVideo dev master commit 15fed957fb allows remote attackers to create recovery codes via HTTP requests. The userRecoverPass.php handler calls setRecoverPass() and saves the user object before Captcha::validation() rejects an incorrect captcha. No authentication or user interaction is required; the request changes any named account's recovery state without sending its owner a recovery email.
