Description
Rojo's "rojo serve" HTTP API (default port 34872) has no Host/Origin header validation, making it vulnerable to DNS rebinding. A malicious webpage can read all project source, write malicious code to files on disk, and launch local programs via opener::open() with no user interaction beyond visiting the page.
