Description Gianluca Gabrielli 2024-07-12 08:14:33 UTC 
+++ This bug was initially created as a clone of Bug #1227687 +++

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.

Comment 1 Gianluca Gabrielli 2024-07-12 08:23:49 UTC 
The following package loads js from polyfill.io.

 - SUSE:SLE-15-SP5:Update/ghc-pandoc

Upstream already address it in v3.1.12.3 [0] but I see that more recently they even droped it [1]. If you believe it's OK to drop, then you can backport the latter commit too.

openSUSE:Factory/ghc-pandoc is safe as it's v3.2.
