Summary Duplicate Advisory: AVideo has Unauthenticated PGP Message Decryption via Public Endpoint ### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-5x2w-37xf-7962. This link is maintained to preserve external references. ### Original Description 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.
