AcyChecker exposes an unauthenticated state-changing operation
AcyChecker through 2.0.0 exposes an operation without the authorization it requires, allowing an unauthenticated request to change protected application state. Version 2.0.1 is fixed. Its prose says the path is unauthenticated while the published CVSS vector encodes low privileges required; this archive retains the stated unauthenticated access and leaves the vector inconsistency unresolved.
