Summary

The FS Product Inquiry WordPress plugin, up to version 1.1.1, does not properly sanitize and escape user input before displaying it on web pages. This oversight can lead to Reflected Cross-Site Scripting (XSS) attacks, potentially exposing high-privilege users, such as administrators, as well as unauthenticated visitors, to malicious scripts. Attackers can exploit this vulnerability to execute arbitrary scripts in the context of the user's browser, which could result in data theft, session hijacking, or other harmful actions.

Affected Version(s)

FS Product Inquiry 0 <= 1.1.1

Exploit Proof of Concept (PoC)
