CVE-2026-7534SUMO Reward Points for WooCommerce <= 32.7.0 - Unauthenticated Stored Cross-Site Scripting via 'reason' Parameter
High 7.2
In plain English
A high-severity cross-site scripting in SUMO Reward Points for WooCommerce from FantasticPlugins. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 0.3% (higher than 25% of all known vulnerabilities).
Official description
The SUMO Reward Points plugin for WordPress is vulnerable to Unauthenticated Stored Cross-Site Scripting via the REST API endpoint `/wp-json/wc-srp/v1/earning` in versions up to, and including, 32.7.0. This is due to the `user_has_cap` filter in the `SRP_REST_Earning_Controller` class unconditionally granting the custom `rs_earning_read` capability to all users — including unauthenticated visitors — combined with missing sanitization of the `reason` parameter in the `create_items()` function and missing output escaping in the `column_default()` method of `SRP_Master_Log`. This makes it possible for unauthenticated attackers to inject arbitrary web scripts into the reward points log that will execute whenever an administrator accesses the Master Log or User Reward Points admin pages.
