What is CVE-2026-88870?

The WWBN AVideo platform has a vulnerability in its LoginControl plugin due to inadequate CSRF token validation on PGP key endpoints. This flaw allows attackers to create malicious pages that, when accessed by a logged-in user, can exploit the savePublicKey.json.php endpoint to change the victim's PGP 2FA public key. If successful, the attacker could potentially lock the user out of their account or compromise it completely if they are aware of the user's password.
