What is CVE-2026-4657?
CVE-2026-4657 is a medium-severity cross-site scripting vulnerability in sunny_johal Easy Google Fonts, published on 10 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-79
