CVE-2025-69443Public exploitNetwork attack vector

Code execution via unauthenticated cross-origin backend requests

Published May 14, 2026 · Updated May 14, 2026

Code injection in coleam00 Archon 0.1.0 through 0.3.11 allows remote attackers to execute commands and read API keys via a crafted web page. The backend service on port 8181 omits authentication and CORS restrictions, so hostile origins can issue localhost requests that disclose configuration and invoke agent and UI APIs. Exploitation requires a victim to access attacker-controlled HTML while the backend is reachable; resulting access includes command execution, UI control, private data, and configured API keys.
