CVE-2026-108695 · Severity: high · CVSS 7.1 · Published 2026-10-11

MultiVendorX is a WordPress plugin that enables multi-vendor marketplace functionality. The plugin contains a flaw that allows vendor accounts to modify critical marketplace settings including commission rates and payout rules by sending requests directly to the settings API endpoint. An attacker with store_owner credentials can exploit this to change platform-wide configuration and potentially redirect payments or alter business rules.

## Technical details

The vulnerability is an incorrect authorization check in the REST API settings controller (/wp-json/multivendorx/v1/settings) that only verifies the edit_stores capability rather than proper platform-level permissions. Vendor accounts with the store_owner role can POST to this endpoint to modify marketplace commission, payout, and onboarding settings. No special privileges, authentication bypass, or user interaction is required beyond having a vendor account; the attack is exploitable over the network via the REST API.
