What fixes it

A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.

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.
