CVE-2026-77183 Details
Description
The FooSales – Point of Sale (POS) for WooCommerce plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.43.0. This is due to the plugin not properly validating a user's identity prior to updating their details like email. This makes it possible for authenticated attackers, with FooSales Cashier-level access and above, to change arbitrary user's email addresses, including administrators, and leverage that to reset the user's password and gain access to their account.
A privilege escalation vulnerability allowing account takeover has been identified in the FooSales Point of Sale (POS) for WooCommerce plugin for WordPress, affecting all versions through 1.43.0. The vulnerability arises because the plugin fails to properly validate a user's identity before allowing changes to account details such as email addresses. This flaw enables authenticated attackers with FooSales Cashier-level access or higher to modify the email addresses of any user, including administrators. Once the email address is changed, the attacker can reset the user's password and gain access to their account.
Users are advised to update the FooSales Point of Sale for WooCommerce plugin to version 1.43.1 or a newer patched version.
