CVE-2026-107645

creativethemeshq Blocksy Companion — Blocksy Companion <= 2.1.58 - Unauthenticated Privilege Escalation to 'role' Parameter

Description · from the CVE record

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.
