CVE-2026-107645

The Blocksy Companion plugin for WordPress is vulnerable to privilege escalation in versions up to, and including, 2.1.58 This is due to the implement user registration() AJAX handler explicitly disabling Dokan's vendor-registration nonce check (via add filter('dokan register nonce check', ' return false')) and then trusting an attacker-supplied $ POST['role'] value when invoking wc create new customer() and wc set customer auth cookie(). This makes it possible for unauthenticated attackers to elevate their privileges to a Dokan 'seller' (vendor) account — including sites where the Dokan vendor signup is explicitly turned off — and to be auto-authenticated into that account, which grants publishing capabilities beyond those of a normal customer.
