CVE-2026-66699

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution WordPress plugin before 5.0.14 does not validate a client-supplied payment amount against the vendor's actual outstanding balance when recording a reverse-withdrawal payment, allowing a vendor to credit their reverse-withdrawal ledger with an arbitrary amount and clear their real commission debt without paying.

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution WordPress plugin before 5.0.14 does not correctly check user capabilities on some of its admin REST API routes, checking only for a WooCommerce management capability instead of the plugin-installation capability, allowing users such as Shop Managers to install and activate arbitrary plugins from WordPress.org.

The Dokan: AI Powered WooCommerce Multivendor Marketplace Solution WordPress plugin before 5.0.14 does not restrict access to per-vendor commission configuration returned by one of its unauthenticated store REST endpoints, allowing any unauthenticated user to disclose a vendor's commission type and, when category-based commission is configured, the per-category and default commission rates.

The Dokan plugin for WordPress up to version 5.0.1 is vulnerable to Privilege Escalation due to a missing authorization check in the `CustomersController` REST controller. It re-registers WooCommerce's customer CRUD routes under the `/dokan/v1/customers/` namespace and replaces WooCommerce's native `manage_woocommerce` capability check with a vendor-only check that inspects the requesting user's role and never validates the target user. Authenticated attackers with Vendor/Seller-level access or above can read, modify, or delete any WordPress user, including administrators, via GET/PUT/DELETE requests against `/wp-json/dokan/v1/customers/{id}`. Setting the `password` parameter on an administrator's record yields a full site takeover.

The Dokan plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) due to improper input neutralization during page generation. This affects versions up to and including 5.0.6.

The Dokan plugin for WordPress up to version 5.0.4 is vulnerable to Insecure Direct Object Reference (IDOR) via the 'id' parameter. Authenticated attackers with subscriber-level access can read other vendors' products, including unpublished drafts and pending listings.

The Dokan plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Product SKU field in all versions up to and including 5.0.4 due to insufficient input sanitization and output escaping. This allows authenticated attackers with custom-level access or higher to inject arbitrary web scripts that execute when users access affected pages.

Dokan versions up to 5.0.2 contain a vulnerability that allows customer privilege escalation.
