@hapi/inert: Static-file confinement bypass via sibling-prefix path

Published Jul 17, 2026 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed
Description
@hapi/inert provides static file and directory handlers for hapi.js. From 4.0.0 to 7.1.0, @hapi/inert serves static files from a directory configured with path in the directory or file handlers or relativeTo for h.file(), with confinement enforced by the confine option, but the confinement check compared the resolved absolute path against the confine directory using a raw string-prefix test, so a sibling directory such as /app/static-secret next to /app/static was incorrectly accepted and could allow an unauthenticated remote attacker to read files via /..%2fstatic-secret/secret.txt. This issue is fixed in version 7.1.1.
