Publication date: 2026-07-11

Last updated on: 2026-07-11

Assigner: Wordfence

Description
The Widgets for Google Reviews plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 13.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Executive Summary

The Widgets for Google Reviews plugin for WordPress has a Stored Cross-Site Scripting (XSS) vulnerability in all versions up to and including 13.3. This vulnerability arises because the plugin does not properly sanitize input or escape output in its admin settings.

Authenticated users with editor-level permissions or higher can exploit this flaw by injecting malicious web scripts into pages. These scripts then execute whenever any user accesses the affected page.

This vulnerability specifically affects multi-site WordPress installations or installations where the unfiltered_html capability has been disabled.

Impact Analysis

This vulnerability can allow attackers with editor-level or higher permissions to inject malicious scripts into web pages, which will execute in the browsers of users who visit those pages.

Such script execution can lead to unauthorized actions such as stealing user credentials, session hijacking, defacement, or spreading malware.

Because the vulnerability requires authenticated access with elevated permissions and affects multi-site or restricted HTML installations, the risk is somewhat limited but still significant for affected environments.

Mitigation Strategies

To mitigate this vulnerability, you should update the Widgets for Google Reviews plugin for WordPress to a version later than 13.3 where the issue is fixed.

Additionally, ensure that only trusted users have editor-level permissions or higher, as the vulnerability requires authenticated attackers with such permissions.

If possible, review your multi-site installations and settings related to unfiltered_html, since the vulnerability only affects multi-site setups or installations where unfiltered_html is disabled.
