Client secret regeneration via nonce-free AJAX request
Published Dec 5, 2022 · Updated Apr 23, 2025
CSRF in WP OAuth Server before 3.4.2 allows remote attackers to regenerate an arbitrary OAuth client secret via an administrator. The wo_regenerate_secret AJAX handler accepts a client ID and rotates its secret without validating a WordPress nonce. Exploitation requires knowledge of the client ID and an authenticated administrator to visit attacker-controlled content; the result is an unplanned credential rotation.
