Subscriber-level unauthorized privileged action
Published Feb 19, 2026 · Updated Feb 19, 2026
Missing authorization in Echo Knowledge Base 16.011.0 and earlier allows remote authenticated users to perform a higher-privileged action. Patchstack has not disclosed the affected function, endpoint, request parameter, or the authorization check that is missing. Subscriber-level access is sufficient; the published consequence is limited to an unspecified higher-privileged action, with no reported data-read or service-interruption effect.
