CVE-2026-7534 Details
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.
A stored cross-site scripting vulnerability has been identified in the SUMO Reward Points plugin for WordPress, affecting versions through 32.7.0. The issue arises in the REST API endpoint '/wp-json/wc-srp/v1/earning', where the 'user_has_cap' filter improperly grants the 'rs_earning_read' capability to all users, including unauthenticated ones. This flaw, combined with inadequate sanitization of the 'reason' parameter in the 'create_items()' function and missing output escaping in the 'column_default()' method of 'SRP_Master_Log', allows unauthenticated attackers to inject arbitrary scripts into the reward points log. These scripts are executed when an administrator views the Master Log or User Reward Points admin pages.
Users are advised to update to version 32.8.0 or a newer patched version.
