Description
The GDPR/DSGVO Compliant, Faster Google Fonts. Easy. plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 6.3.11. This is due to admin notices being echoed without escaping, while the notices set when a font file download fails include the font file URL and a filename built from the font family name, both taken from the processed stylesheet. This makes it possible for authenticated attackers, with contributor-level access and above, who can get a stylesheet from a host they control processed (see the Server-Side Request Forgery fixed in the same release), to inject arbitrary web scripts that execute when an administrator loads a wp-admin page shortly afterwards.
