Technical details

The vulnerability is an unprotected alternate channel (CWE-420) where authenticated requests via alternate API paths bypass gateway-level security controls including session enforcement and revocation validation. An authenticated user with low privileges can reach REST API endpoints over request paths where these controls are not applied, requiring network access and valid authentication but no additional user interaction. A patch is available in version 9.5.1.
