Account manipulation via missing nonce validation

Published Oct 24, 2024 · Updated Apr 8, 2026

Cross-site request forgery in MultiVendorX 4.2.4 and earlier allows remote attackers to alter vendor accounts through forged requests. Several functions in api/class-mvx-rest-controller.php process account-changing requests without correct WordPress nonce validation. Exploitation requires a site administrator to follow or activate a crafted request and can update vendor details, create vendor accounts, or delete users.
