What happened?

Hi,

IMO this fork of https://github.com/kangax/html-minifier is still vulnerable to CVE-2022-37620 as the regex in the candidate variable is still the same.

It seems the CVE record differs from https://security.snyk.io/vuln/SNYK-JS-HTMLMINIFIER-3091181, which contains more details.

Not sure why this is the case. I will clarify with Snyk.

The described PoC does not work with html-minifier-terser:

import { minify } from 'html-minifier-terser';
result = minify(attrName = '\t'.repeat(547703) + '.\t1x', tag = '\t'.repeat(547703) + '.\t1x'  )

But with valid code, the PoC works:

import { minify } from 'html-minifier-terser';
const result = minify('\t'.repeat(547703) + '.\t1x')

It seems no one really confirmed the actual issue here. See my addition regarding the candidate variable: kangax/html-minifier#1135 (comment)
