WWBN AVideo contains a broken access control vulnerability in videoViewsInfo endpoints that returns complete user records including password hashes, recovery tokens, and live session identifiers to unauthenticated callers when a hash parameter is provided. Attackers can use the disclosed session identifier to hijack viewer sessions, including administrator accounts, and obtain sensitive personal data for all video viewers.
