The vulnerability was discovered and publicly disclosed on April 4, 2022. The issue affects the plugin's settings functionality, specifically in areas like the "Referer address" field, which lacks proper sanitization and escaping mechanisms (WPScan).

The technical nature of the vulnerability involves improper neutralization of input during web page generation, which can be exploited even when the unfiltered_html capability is disallowed (NVD).

The vulnerability allows high-privilege users to perform Cross-Site Scripting attacks through unsanitized plugin settings.
