CVE-2026-95687: WPC Shop as a Customer for WooCommerce <= 2.0.0 - Authenticated (Subscriber+) Privilege Escalation via Missing Role Check on Target User to wpcsa_login AJAX Endpoint
The WPC Shop as a Customer for WooCommerce plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 2.0.0 This is due to the plugin not properly validating the target user's role prior to issuing a new authentication session, allowing an authenticated attacker to log in as any WordPress Administrator by directly supplying an Administrator's user ID to the wpcsalogin endpoint and receiving a full Administrator session cookie without supplying the Administrator's password. This makes it possible for authenticated attackers to perform a direct session takeover, gaining full Administrator-level access to the site.
