Sensitive data disclosure via missing REST authorization
Published Mar 25, 2026 · Updated Mar 25, 2026
Missing authorization in WPVulnerability 4.2.1 and earlier allows remote authenticated users to read sensitive site vulnerability data. Its REST API permission callback verifies authentication but omits manage_options or manage_network_options checks before returning endpoint data. Subscriber-level access with a valid session or application password is sufficient, and the reported consequence is disclosure of vulnerability data.
