4th percentile - higher than 4% of all known CVEs

The ultimate-woocommerce-auction-pro WordPress plugin through version 2.4.5 does not sanitize and escape a parameter before outputting it back on the page, leading to a reflected Cross-Site Scripting vulnerability. This can be exploited against high privilege users such as admins.

Exploitation of this vulnerability could lead to admin account takeover and allow attackers to execute malicious code in the victim's browser context, posing a serious security threat to the organization.

It is recommended to update the plugin to the latest version that includes security fixes and to conduct a security audit of the application to identify and mitigate potential threats.
