Summary

The Free Quotation plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.1.6 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Risk Assessment

An attacker with administrator privileges can inject malicious scripts that execute in the browsers of users visiting infected pages, potentially leading to session or data theft. However, this requires high privileges and a specific WordPress configuration.

Recommendation

Update the Free Quotation plugin to a version later than 3.1.6 or remove it if not used. Consider enabling unfiltered_html only for trusted users.
