CVE-2026-107645Blocksy Companion <= 2.1.58 - Unauthenticated Privilege Escalation to 'role' Parameter
Critical 9.1
In plain English
A critical-severity privilege mismanagement in Blocksy Companion from creativethemeshq. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 23% of all known vulnerabilities).
Official description
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.
