  "details": "### Impact\nThe two parsers resolved duplicates inconsistently and silently:\n- `Content.disposition()` retained the last occurrence of each parameter.\n- `Content.type()` retained the first occurrence of charset and boundary.\n\nEither behavior creates a parameter-smuggling primitive when another component in the request-processing chain (a WAF, reverse proxy, security filter, or alternate parser) resolves duplicates the opposite way. The primary attack vector is upload filename allowlist bypass:\n\n`Content-Disposition: form-data; name=\"file\"; filename=\"safe.txt\"; filename=\"shell.php\"`\n\n### Patches\nThe issue has been patched in 6.0.2.\n\n### Workarounds\nPre or post validate headers looking for duplicates.\n\n### Resources\n- [RFC 6266 \u00a74.1 \u2014 Content-Disposition syntax](https://www.rfc-editor.org/rfc/rfc6266#section-4.1)\n- [RFC 7231 \u00a73.1.1.1 \u2014 Content-Type syntax](https://www.rfc-editor.org/rfc/rfc7231#section-3.1.1.1)\n- [RFC 7230 \u00a73.2.6 \u2014 token character set](https://www.rfc-editor.org/rfc/rfc7230#section-3.2.6)",
