QCubed 2.2.0 through 3.1.1 contains a reflected cross-site scripting vulnerability that allows unauthenticated attackers to inject scripts through the installation_path parameter. Attackers can craft GET requests to /assets/php/_devtools/installer/step_2.php with malicious installation_path values echoed unescaped, executing JavaScript in victims' browsers. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-20.
