# @hapi/content: crafted Content-Disposition header can block Node.js event loop

A crafted Content-Disposition header with a long token and no equals sign makes @hapi/content's parser run in quadratic time. The Node.js event loop stalls, so the server stops answering other requests.

_Summary, check and fix written by a model from the sources; labelled as such._

## Fix

- @hapi/content: upgrade to `6.0.3`

## Timeline

- 2026-10-29T21:26:51+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-119202

## From the sources

@hapi/content provides HTTP Content-* header parsing. From 3.0.6 until 6.0.3, Content.disposition() uses an unanchored parameter-name expression in a global regular-expression scan, causing repeated failed matching over the remaining input when a Content-Disposition parameter contains a long token without an equals sign. The resulting quadratic processing can block the Node.js event loop before route handlers or validation when @hapi/pez parses multipart/form-data headers, including unauthenticated hapi routes with payload.multipart enabled, and also affects applications that pass untrusted headers directly to Content.disposition(). This issue is fixed in @hapi/content version 6.0.3.
