Stored XSS in FlyEnv before 4.18.0 allows remote attackers to execute arbitrary JavaScript in the Electron renderer process by injecting unsanitized HTML through markdown sources or AI chat messages rendered via Vue v-html directives. Because FlyEnv's Electron renderer operates with Node.js API integration active, exploitation escalates beyond conventional XSS to effective local code execution with unrestricted filesystem access on the developer's machine. A publicly available exploit exists at GitHub issue #809, and vendor-released patch v4.18.0 addresses the flaw.
