CVE-2026-1926: CWE-862 Missing Authorization in wpswings Subscriptions for WooCommerce
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.
AI Analysis
Technical Summary
CVE-2026-1926 describes a missing authorization vulnerability in the Subscriptions for WooCommerce plugin for WordPress. The vulnerable function wps_sfw_admin_cancel_susbcription() is triggered on the init action but lacks proper capability checks and nonce validation, allowing unauthenticated attackers to cancel active subscriptions by crafting GET requests with arbitrary nonce values. This affects all versions up to and including 1.9.2.
Potential Impact
The vulnerability allows unauthenticated attackers to cancel any active WooCommerce subscription without authorization. This results in unauthorized modification of subscription data (integrity impact) but does not affect confidentiality or availability. The CVSS 3.1 base score is 5.3 (medium severity), reflecting the network attack vector, no privileges required, no user interaction, and limited impact to integrity only.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor vendor communications for updates. Until a fix is available, restricting access to the affected plugin's functionality and disabling or limiting the init hook execution for this function may reduce risk. Avoid exposing the plugin to untrusted users or anonymous requests.
