No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

A reflected cross-site scripting vulnerability exists in x-ui 0.3.2. The management interface reflects the raw request URI into a client-side template binding expression used for sidebar menu highlighting. Server-side HTML entity escaping is ineffective in this context: the browser decodes the entities before the client-side framework evaluates the content as a JavaScript expression. A logged-in panel user who visits a crafted URL allows arbitrary script execution in the same-origin context of the management page, enabling data theft and unauthorized actions through the victim's session.

Exploitation none (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
