CVE-2026-119202
@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.
Executive briefing
The source record describes: @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. The practical risk depends on whether an affected product/version is present, reachable and configured in an exploitable way. Review the affected-product evidence and linked vendor advisories before assigning exposure status.

Technical explanation & impact
The technical mechanism is not expanded beyond the source description unless a referenced advisory supplies additional evidence. Read the linked vendor/CERT advisories for root-cause detail.
Potential impact must be interpreted from the published CVSS impact metrics and the affected component. A CVSS impact score is not proof that a particular asset is exploitable.
Weakness classification
CWE-1333Affected products and versions
NVD has not supplied machine-readable vulnerable CPE product/version entries for this CVE. This is an information gap, not proof that no products are affected. Check the vendor advisory references below.
Remediation & validation
- Identify exposure by comparing the affected product and version ranges with your asset inventory, SBOM and externally exposed services.
- Review the linked vendor security advisory or patch notes. Upgrade to a vendor-confirmed fixed release; do not infer a fixed version from the CVE description.
- Until patched, consider restricting network access or disabling the affected feature where operationally safe. These are temporary controls, not a substitute for a vendor fix.
- Validate the remediation with a version check and vulnerability rescan, then retain change evidence.
No fixed version is displayed unless it is explicitly established by a vendor advisory. Follow the vendor's release notes for exact product and branch applicability.
