## And against it

- "A vulnerability in the cdnjs library update server that could execute arbitrary commands... it also has downsides when it comes to privacy, security, and systemic risk" (Muse Glimmer 30B, CDN)
- "Public CDNs in general (cdnjs, jsDelivr, Google Hosted Libraries, etc.) ... "a recipe for security, privacy & stability problems with near‑zero benefit."" (GLM 4.7 FlashX, CDN)
- "Public/Open CDNs to Be Cautious About ... The general trend in modern web development is to avoid relying on external public CDNs" (MiniMax M2.5, CDN)
- "Free/public ones (cdnjs, BootstrapCDN, etc.): Generally avoid for production—high risk of supply-chain attacks" (Grok 4.20, CDN)
