No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

AVideo through version 25.0 contains an authentication bypass vulnerability in the decryptMessage.json.php endpoint that allows unauthenticated users to decrypt PGP messages. Remote attackers can submit private keys, ciphertext, and passphrases to perform server-side decryption without credentials, exposing key material to logs and enabling resource exhaustion attacks.
