Critical: Loading scripts from mutable Gist URLs poses a significant supply chain security risk.
This implementation has several serious concerns:
-
Mutable content: The
/raw/URL serves the latest gist revision. The gist owner (or anyone who gains access) can modify the script at any time, and those changes would immediately execute in all users' browsers. -
No integrity verification: Without a Subresource Integrity (SRI) hash, there's no way to detect if the script has been tampered with.
-
Unofficial CDN: githack.com explicitly warns it's not intended for production use and offers no uptime guarantees.
-
PR title indicates "test CDN": If this is for testing, it should not be merged to master without a production-ready hosting solution.
Recommended approach:
- Host the script on controlled infrastructure (e.g., your own CDN, npm package, or versioned asset in this repository)
- If an external CDN is required, use a pinned version URL with an
integrityattribute - Add a
strategyprop to control script loading behavior
