Description

Impact

Npm users of PUC 1.17.3 or PUC latest were briefly affected by crypto-related malware detailed in the blog post below. This includes the extremely popular jsdelivr hosting of this file.

Patches

We unpublished the version on npm.

Workarounds

This has already been unpublished. See Prebid.js 9 release notes for suggestions on moving off the deprecated workflow of using the PUC or pointing to a dynamic version of it. PUC users pointing to latest should transition to 1.17.2 ASAP to avoid similar attacks in the future.
