The polyfill.js is a popular open source library to support older browsers. 100K+ sites embed it using the cdn.polyfill.io domain. Notable users are JSTOR, Intuit and World Economic Forum. However, in February this year, a Chinese company bought the domain and the Github account. Since then, this domain was caught injecting malware on mobile devices via any site that embeds cdn.polyfill.io. Any complaints were quickly removed (archive here) from the Github repository.
One place I worked at recently was still using Node version 8. Running
npm installwould give me a mini heart attack… Like 400+ critical vulnerabilities, it was several thousand vulnerabilities all around.After the first 100, the other 300 kinda don’t matter.
If you’re on RHEL 8+, you can install the latest version of node with dnf.
dnf install nodejswill likely install node 8 :(. Usednf module install nodejs:20to install the latest version.
