Unauthenticated private-message disclosure via unchecked identifier

Published Aug 29, 2022 · Updated Aug 3, 2024

IDOR in the Sensei Messages REST endpoint in Automattic Sensei LMS before 4.5.0 allows remote attackers to read private teacher messages. The route at /wp-json/wp/v2/sensei-messages/ accepts an attacker-controlled message identifier and returns the referenced record without the required permission check. No authentication or user interaction is required; successful requests disclose message content but provide no reported write access or service interruption.
