A Regular Expression Denial of Service (ReDoS) flaw was found in kangax html-minifier 4.0.0 via the candidate variable in htmlminifier.js.
The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Html-minifier | Html-minifier_project | 4.0.0 (including) | 4.0.0 (including) |
Attackers can create crafted inputs that
intentionally cause the regular expression to use
excessive backtracking in a way that causes the CPU
consumption to spike.
