MultiVendorX WordPress plugin through 5.0.19 contains an incorrect authorization vulnerability that allows vendor accounts to modify marketplace-wide settings via the settings REST endpoint. Attackers with the store_owner role can send POST requests to /wp-json/multivendorx/v1/settings, gated only by edit_stores, to overwrite commission, payout, and onboarding settings.
