What is CVE-2026-119202?
CVE-2026-119202 is a high-severity vulnerability in hapijs content, published on 29 Oct 2026.
Official description
@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.
