Advisories for Npm/Css-What package

The package css-what before 2.1.3 is vulnerable to Regular Expression Denial of Service (ReDoS) due to the usage of insecure regular expression in the re_attr variable of index.js. The exploitation of this vulnerability could be triggered via the parse function.

The css-what package for Node.js does not ensure that attribute parsing has linear time complexity relative to the size of the input.
