Description
Prebid.js is a free and open source library for publishers to quickly implement header bidding. NPM users of prebid 10.9.2 may have been briefly compromised by a malware campaign. The malicious code attempts to redirect crypto transactions on the site to the attackers' wallet. Version 10.10.0 fixes the issue. As a workaround, it is also possible to downgrade to 10.9.1.
