The CVE-2025-XXXX vulnerability exists within the `lib/rest/routes/apps.js` file of ExpressGateway’s REST API endpoint. The flaw is a reflected Cross-Site Scripting (XSS) issue stemming from improper neutralization of user-supplied input. Specifically, the endpoint fails to sanitize data passed in a request before directly embedding it into the HTML response sent back to the user’s browser. An attacker can craft a malicious URL containing a JavaScript payload as a parameter. When an authenticated administrator is tricked into clicking this link, the payload is executed within their browser session in the context of the ExpressGateway application, allowing for session hijacking or unauthorized actions.
