CVE-2013-4660: Input Validation
First published: Fri Jun 28 2013(Updated: )
The JS-YAML module before 2.0.5 for Node.js parses input without properly considering the unsafe !!js/function tag, which allows remote attackers to execute arbitrary code via a crafted string that triggers an eval operation.
