GHSA-mwjc-5j4x-r686: AVideo has an unauthenticated decrypt oracle leaking any ciphertext

March 20, 2026

The API plugin exposes a decryptString action without any authentication. Anyone can submit ciphertext and receive plaintext. Ciphertext is issued publicly (e.g., view/url2Embed.json.php), so any user can recover protected tokens/metadata. Severity: High.
