Stored XSS in Easy Google Fonts WordPress Plugin

Publication date: 2026-09-10

Last updated on: 2026-09-10

Assigner: Wordfence

Description
The Easy Google Fonts plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the control_selectors meta field in all versions up to, and including, 2.0.4. This is due to the plugin registering the control_selectors meta field with show_in_rest enabled but without a sanitize_callback, and subsequently outputting this unsanitized data directly into <style> tags on the frontend without proper escaping. This makes it possible for authenticated attackers, with Author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Executive Summary

The Easy Google Fonts WordPress plugin has a stored cross-site scripting (XSS) vulnerability due to improper handling of the control_selectors meta field. The plugin registers this field with show_in_rest enabled but lacks a sanitize_callback, allowing unsanitized data to be output directly into style tags on the frontend without proper escaping. This enables authenticated attackers with Author-level access or higher to inject malicious scripts.

Impact Analysis

If exploited, this vulnerability allows attackers to inject malicious scripts into your WordPress site. These scripts can execute whenever a user visits an affected page, potentially stealing user data, session cookies, or performing actions on behalf of users. It requires Author-level access or higher to exploit.

Compliance Impact

This vulnerability could lead to unauthorized access to user data, which may violate GDPR's data protection requirements or HIPAA's safeguards for protected health information. A successful exploit could result in data breaches, triggering compliance violations and potential legal penalties.

Mitigation Strategies

Update the Easy Google Fonts plugin to the latest version, which should address the vulnerability. If updating is not immediately possible, consider disabling the plugin temporarily until an update is applied.
