Vulnerability Title
OMGF | GDPR/DSGVO Compliant, Faster Google Fonts. Easy. <= 6.3.10 - Unauthenticated Stored Cross-Site Scripting via 's' Search Parameter in comments-atom Feed
Source: CVE Program / CVE List V5
Vulnerability Description
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.
