Subscriber-level admin action access via unchecked AJAX handlers
Published Jan 19, 2023 · Updated Apr 8, 2026
Authorization bypass in Events Made Easy 2.3.16 and earlier allows remote authenticated users to invoke administrator-only AJAX actions. Several AJAX handlers execute privileged plugin functions without verifying the caller's configured WordPress capability. Subscriber-level access is sufficient, and the reported consequence is limited to unauthorized data access or modification through those exposed actions.
