Before the patch, the confinement check compared the resolved absolute path against the confine directory using a raw string-prefix test, so a sibling directory whose absolute path begins with the same characters as the confine directory (eg. `/app/static-secret` next to a served `/app/static`) was incorrectly accepted as confined. An unauthenticated remote attacker who knows or guesses such a sibling name can read any file inside it via a request like `/..%2fstatic-secret/secret.txt`, provided the file is readable by the server process. Only applications that happen to have a sibling directory sharing a string prefix with the served directory are exploitable; applications with no such sibling are unaffected.\n\n### Patches\nUpgrade to 7.1.1.\n\n### Workarounds\nFor users who cannot upgrade immediately: ensure the directory served via inert has no sibling whose name starts with the same characters (for example, rename `static-secret/` to `secret/`, or move it to a different parent directory).\n\n### Resources\nPull Request: https://github.com/hapijs/inert/pull/176","state":0,"publishedAt":"2026-06-11T17:10:15+00:00","modifiedAt":"2026-09-10T03:50:50.4450116+00:00","affected":[{"ecosystem":"npm","name":"@hapi/inert","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"4.0.0"},{"kind":"fixed","version":"7.1.1"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/hapijs/inert/security/advisories/GHSA-rcvq-m9j9-6f4g","https://github.com/hapijs/inert/pull/176","https://github.com/hapijs/inert/commit/a65e5b271b5c3405af463469959c5e052eb23a62","https://github.com/hapijs/inert"],"sourceUrl":"https://github.com/advisories/GHSA-rcvq-m9j9-6f4g","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-rcvq-m9j9-6f4g","identifiers":["GHSA-rcvq-m9j9-6f4g","CVE-2026-48049"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
