The plugin fails to sanitize or escape this input, allowing arbitrary JavaScript to be injected into the browser when a user visits a malicious page that auto\u2011submits the form to the vulnerable site.

The EPSS score is below 1\u202f%, reflecting a low likelihood of exploitation at the time of analysis, and the issue is not yet listed in the CISA KEV catalog. Attackers can exploit the flaw through unauthenticated access by delivering a crafted POST request embedded in a malicious page that automatically sends the data to the site.
