Description

GoAdmin through 1.2.26 fails to properly anchor the logout pattern when checking permissions, allowing authenticated users to bypass permission checks by appending a query parameter. Attackers can append a query string containing the admin prefix followed by /logout to reach administrative endpoints and perform unauthorized actions including reading sensitive data and modifying application state.
