## Affected

- FantasticPlugins SUMO Reward Points for WooCommerce: through 32.7.0

## 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.
