CVE-2024-56043Network attack vector

Administrator account creation via caller-controlled default role

Published Dec 31, 2024 · Updated Apr 28, 2026

Incorrect privilege assignment in VibeThemes WPLMS 1.9.9 and earlier allows remote attackers to register Administrator accounts. The wplms_register_user function copies a caller-controlled default_role setting into the registration role field passed to wp_insert_user. The unauthenticated AJAX action accepts the crafted registration request when its signup nonce is valid, granting complete WordPress site control through the new account.
