- CVE-2026-89417, 7 Oct 2026
- The OMGF | GDPR/DSGVO Compliant, Faster Google Fonts. Easy. plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 's' Search Parameter via comments-atom Feed in all versions up to, and including, 6.3.10 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires that the front-end server serves the retained .tmp file without a Content-Type or X-Content-Type-Options header, enabling MIME-sniffing browsers such as Chromium to execute the injected script - a condition present by default on many Apache and nginx/php-fpm deployments. CVE record
- CVE-2026-91828, 2 Oct 2026
- The OMGF | GDPR/DSGVO Compliant, Faster Google Fonts. Easy. WordPress plugin before 6.3.11 does not require authentication or a valid nonce on an action that issues a slow server-side loopback request, allowing unauthenticated attackers to exhaust the site's PHP worker pool and make the entire site unavailable. CVE record
- CVE-2023-6600, 3 Jan 2024
- The OMGF | GDPR/DSGVO Compliant, Faster Google Fonts. Easy. plugin for WordPress is vulnerable to unauthorized modification of data and Stored Cross-Site Scripting due to a missing capability check on the update_settings() function hooked via admin_init in all versions up to, and including, 5.7.9. This makes it possible for unauthenticated attackers to update the plugin's settings which can be used to inject Cross-Site Scripting payloads and delete entire directories. PLease note there were several attempted patched, and we consider 5.7.10 to be the most sufficiently patched. CVE record
- CVE-2021-24638, 20 Sep 2021
- The OMGF WordPress plugin before 4.5.4 does not escape or validate the handle parameter of the REST API, which allows unauthenticated users to perform path traversal and overwrite arbitrary CSS file with Google Fonts CSS, or download fonts uploaded on Google Fonts website. CVE record
- CVE-2021-24639, 20 Sep 2021
- The OMGF WordPress plugin before 4.5.4 does not enforce path validation, authorisation and CSRF checks in the omgf_ajax_empty_dir AJAX action, which allows any authenticated users to delete arbitrary files or folders on the server. CVE record
What to do if you run OMGF
If you run OMGF, open WordPress and check the installed version in Plugins. Compare it with the affected versions in the vulnerability record. If a fixed version is available, take a current backup and update to that version or the latest supported release.
If no fixed version exists, consider disabling and removing the plugin or replacing it with a maintained alternative. After dealing with the affected software, check administrator users, unexpected file changes, redirects, unfamiliar pages and security logs for signs that the site may already have been altered.
