Detection Guidance

This vulnerability is a reflected Cross-site Scripting (XSS) issue in the Bricks Builder WordPress theme versions 2.2 and below. Detection typically involves monitoring for suspicious HTTP requests containing malicious scripts or payloads that attempt to exploit the XSS flaw.

Since the vulnerability requires user interaction such as clicking a crafted link, network detection can include inspecting web traffic for unusual query parameters or payloads that include script tags or JavaScript code.

Specific commands are not provided in the available resources, but common approaches include using web application firewalls (WAF) with rules targeting XSS patterns or employing tools like curl or wget to test for reflected script injection by sending crafted requests to the vulnerable endpoints.
