At a glance

CVE-2026-1926 is a medium-severity Missing Authorization vulnerability in the Subscriptions for WooCommerce WordPress plugin, affecting versions <= 1.9.2. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 1.9.3; sites on affected versions should update now. Disclosed March 2026, reported by shrikant bhosale.

Vulnerability Overview

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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.

CWE-862: Missing Authorization

Subscriptions for WooCommerce <= 1.9.2 carries this weakness at wps_sfw_admin_cancel_susbcription(), and reaching it takes no account at all. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Subscriptions for WooCommerce the fix is 1.9.3: builds <= 1.9.2 are affected, anything from 1.9.3 onward is not.

Remediation

Update to version 1.9.3, or a newer patched version

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. None of that substitutes for the fix: Subscriptions for WooCommerce 1.9.3 closes this, and updating the plugin is the step that ends it.
