What is CVE-2026-1926?
CVE-2026-1926 is a medium-severity missing authorization vulnerability in wpswings Subscriptions for WooCommerce, published on 18 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
