Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

AVideo versions up to and including 26.0 expose a decryptString action in the API plugin without authentication. An anonymous remote attacker can submit ciphertext, such as the playLink values that the platform publicly issues, and receive the plaintext back, which may include tokens or metadata meant to stay confidential. No fixed version is listed; the source suggests restricting or removing the endpoint, and rotating encryption keys after a patch.
