Description
@hapi/content from 6.0.1 before 6.0.3 contains a regular expression denial of service vulnerability in Content.disposition() caused by an incomplete fix for CVE-2026-35213. Unauthenticated remote attackers can send multipart uploads with a long Content-Disposition parameter lacking an equals sign, triggering quadratic backtracking that blocks the event loop.
