Executive brief
The Subscriptions for WooCommerce WordPress plugin fails to properly validate the shared secret protecting its REST API endpoint, allowing attackers to retrieve sensitive subscription data without authentication. This exposes customer usernames, product names, payment amounts, and billing dates, potentially compromising customer privacy and enabling targeted fraud or social engineering attacks.
Technical details
The vulnerability is a REST API authentication bypass caused by improper validation of a shared secret used to protect a subscription data endpoint. The authentication mechanism in versions before 2.0.3 can be bypassed by unauthenticated users through a network request, allowing full retrieval of subscription records stored in the WooCommerce database. An attacker requires only network access to the WordPress site and no user interaction or prior authentication. The impact is disclosure of sensitive subscription metadata including customer identifiers, product details, and payment information. A patch is available in version 2.0.3 and later.
