{"cve":"CVE-2026-4657","nvd":{"published":"2026-09-10T04:18:04.410","modified":"2026-09-10T18:18:01.710","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["https://plugins.trac.wordpress.org/browser/easy-google-fonts/tags/2.0.4/src/includes/data.php#L214","https://plugins.trac.wordpress.org/browser/easy-google-fonts/tags/2.0.4/src/includes/data.php#L24","https://plugins.trac.wordpress.org/browser/easy-google-fonts/tags/2.0.4/src/includes/data.php#L72","https://plugins.trac.wordpress.org/browser/easy-google-fonts/tags/2.0.4/src/includes/frontend.php#L185","https://plugins.trac.wordpress.org/browser/easy-google-fonts/tags/2.0.4/src/includes/settings.php#L123"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:53.108888569+00:00"},"epss":{"cve":"CVE-2026-4657","score":0.00419,"percentile":0.36221,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
