Prebid Universal Creative (PUC) is a JavaScript API to render multiple formats. Npm users of PUC 1.17.3 or PUC latest were briefly affected by crypto-related malware. This includes the extremely popular jsdelivr hosting of this file. The maintainers of PUC unpublished version 1.17.3. Users should 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 as soon as possible to avoid similar attacks in the future.
CVE-2025-59039
This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 0.3%, top 77% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
