Will the Polyfill supply chain attack impact OJS/OMP/OPS?

I’m reading the reports about Polyfill supply chain attack, and a quick grep on files in our OJS install shows that it is called a few times. Does anyone know what impact this will have on users, and what we can do to mitigate?

Hi @Wendy,

“Polyfill” is a generic term, and the polyfill.io library is a single example of a library providing polyfills for Javascript. I don’t believe the library in question is included in OJS, and in any case, we are not using CDNs for library delivery, but I’ll tag @jardakotesovec for a second opinion.

We do have e.g. https://www.npmjs.com/package/@babel/helper-define-polyfill-provider distributed with OJS, but that’s a different library.
