Name of the Vulnerable Software and Affected Versions The SEO Plugin by Squirrly SEO versions prior to 11.1.12

Description The issue is related to a Reflected Cross-Site Scripting problem. It occurs because the type parameter is not properly escaped before being outputted back in an attribute on an admin page. This can lead to malicious script execution.

Recommendations For versions prior to 11.1.12, update to version 11.1.12 or later to resolve the issue. As a temporary workaround, consider restricting access to the admin page where the type parameter is used until the update is applied.
