Description
The MultiVendorX – WooCommerce Multivendor Marketplace AI Powered Solutions plugin for WordPress is vulnerable to unauthorized modification of data in versions 5.0.0 through 5.0.18 due to the set_modules REST route using a permission check that also accepts the store owner 'edit_stores' capability. This makes it possible for authenticated attackers, with store owner-level access, to activate or deactivate marketplace-wide modules, a function intended only for administrators.
