CVE-2026-69116Public exploitNetwork attack vector

Renderer script execution via unsanitized v-html content

Published Aug 10, 2026 · Updated Aug 10, 2026

Cross-site scripting in FlyEnv before 4.18.0 allows remote attackers to execute scripts through crafted markdown or AI chat content. The markdown renderer enables raw HTML and passes its output, along with raw chat item content, to Vue v-html sinks without sanitization. Execution requires a user to load attacker-controlled content, such as a response from a malicious Ollama-compatible server; renderer scripts can reach exposed Node.js IPC methods and filesystem operations.
