The milolibs query param was interpolated directly into a template literal used for a dynamic import(), letting an attacker point module loading at an arbitrary origin and execute JS in the page context. Add a strict whitelist (^[a-zA-Z0-9_-]+$) and throw on invalid input in express/code/scripts/utils.js. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
