CVE-2022-34867Network attack vector

Submission disclosure and deletion via permissive REST callbacks

Published Sep 6, 2022 · Updated Apr 28, 2026

Sensitive information exposure in WP Libre Form 2 2.0.0 through 2.0.8 allows remote attackers to list and delete form submissions. The REST route registrations set a second permission_callback to __return_true, overriding currentUserIsAllowedToUse for submission operations. No authentication or user interaction is required, exposing stored submissions to reading or deletion over the network.
