CVE-2024-31380Network attack vector

Authenticated PHP execution via unchecked Edit Only access

Published Apr 3, 2024 · Updated Apr 28, 2026

Code injection in Soflyy Oxygen Builder 4.9 and earlier allows remote authenticated users with builder access to execute arbitrary PHP code. The wp_ajax_ct_exec_code handler passes a base64-decoded request code value directly to eval after oxygen_vsb_current_user_can_access accepts Edit Only mode. An account granted Client Control builder access, including Edit Only access, can take over the WordPress site and underlying server.
