Vulnerability Title
Subscriptions for WooCommerce <= 1.9.2 - Missing Authorization to Unauthenticated Arbitrary Subscription Cancellation
Source: CVE Program / CVE List V5
Vulnerability Description
The Subscriptions for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `wps_sfw_admin_cancel_susbcription()` function in all versions up to, and including, 1.9.2. This is due to the function being hooked to the `init` action without any authentication or authorization checks, and only performing a non-empty check on the nonce parameter without actually validating it via `wp_verify_nonce()`. This makes it possible for unauthenticated attackers to cancel any active WooCommerce subscription by sending a crafted GET request with an arbitrary nonce value via the `wps_subscription_id` parameter.
