CVE-2026-108695 Details
Description
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.
A vulnerability exists in the MultiVendorX WordPress plugin, specifically in versions through 5.0.19. This vulnerability allows vendor accounts with the store_owner role to improperly access and modify marketplace-wide settings through the settings REST endpoint. The issue arises because the plugin's authorization checks mistakenly allow vendors to overwrite global settings such as commission and payout structures, which should be restricted to administrators.
Users are advised to update the MultiVendorX WordPress plugin to version 5.0.20 or later, where this vulnerability has been addressed.
