Technical details

The vulnerability is a reflected or stored cross-site scripting (XSS) flaw in the HTML artifact preview rendering component of Moonshot AI Kimi. The vulnerable component fails to properly sanitize or encode HTML content when rendering artifacts in the public share view.

The attack vector is network-based and requires only that a victim click a malicious link or visit a shared artifact URL. No patch information is currently available in the advisory.
