Summary

The Embed Swagger WordPress plugin is vulnerable to Reflected Cross-Site Scripting due to insufficient escaping/sanitization and validation via the url parameter found in the ~/swagger-iframe.php file which allows attackers to inject arbitrary web scripts onto the page, in versions up to and including 1.0.0.
