CVE, Research URL: CVE-2026-6072
Home page URL: Security reports for Oliver POS – A WooCommerce Point of Sale (POS)
Application: Oliver POS – A WooCommerce Point of Sale (POS)
Date: May 20, 2026
Research Description: The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.4.2.6. The plugin protects its entire /wp-json/pos-bridge/* REST API namespace through the oliver_pos_rest_authentication() permission callback, which uses a loose PHP comparison (==) to compare the attacker-supplied 'OliverAuth' header value against the 'oliver_pos_authorization_token' option. On fresh installations where the admin has not yet completed the connection flow, this option is unset (get_option returns false). Due to PHP's type juggling, the loose comparison '0' == false evaluates to true, allowing an unauthenticated attacker to bypass authentication by sending 'OliverAuth: 0'. This grants full access to all POS API endpoints, enabling attackers to read user data (including administrator details), update user profiles (including email addresses), and delete non-admin users. An admin account email reset can lead to site takeover.
Affected versions: max 2.4.2.6.
Status: vulnerable

CVE, Research URL: CVE-2024-13513
Home page URL: Security reports for Oliver POS – A WooCommerce Point of Sale (POS)
Application: Oliver POS – A WooCommerce Point of Sale (POS)
Date: Feb 15, 2025
Research Description: The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4.2.3 via the logging functionality. This makes it possible for unauthenticated attackers to extract sensitive data including the plugin's clientToken, which in turn can be used to change user account information including emails and account type. This allows attackers to then change account passwords resulting in a complete site takeover. Version 2.4.2.3 disabled logging but left sites with existing log files vulnerable.
Affected versions: max 2.4.2.4.
Status: vulnerable
