Mitigation checklist
- Validate and limit the length of any user-controlled input before passing it to decode-uri-component's decode() function. Inputs containing more than approximately 200 percent-encoded tokens (e.g. '%ab' sequences) can trigger noticeable delays. Reject or truncate URI components exceeding a reasonable length threshold before decoding. A fix exists in the upstream repository (commit fa479daf) but has not yet been included in an npm release.
