{"id":"GHSA-rcvq-m9j9-6f4g","summary":"@hapi/inert has a static-file confinement bypass via sibling-prefix path","details":"### Impact\n`@hapi/inert` serves static files from a directory configured with `path` (in the `directory` / `file` handlers) or `relativeTo` (for `h.file()`), with confinement enforced by the `confine` option (default `true`). 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","aliases":["CVE-2026-48049"],"modified":"2026-09-10T03:50:50.445011616Z","published":"2026-06-11T17:10:15Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-11T17:10:15Z","nvd_published_at":null,"cwe_ids":["CWE-22"]},"references":[{"type":"WEB","url":"https://github.com/hapijs/inert/security/advisories/GHSA-rcvq-m9j9-6f4g"},{"type":"WEB","url":"https://github.com/hapijs/inert/pull/176"},{"type":"WEB","url":"https://github.com/hapijs/inert/commit/a65e5b271b5c3405af463469959c5e052eb23a62"},{"type":"PACKAGE","url":"https://github.com/hapijs/inert"}],"affected":[{"package":{"name":"@hapi/inert","ecosystem":"npm","purl":"pkg:npm/%40hapi/inert"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0"},{"fixed":"7.1.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-rcvq-m9j9-6f4g/GHSA-rcvq-m9j9-6f4g.json","last_known_affected_version_range":"\u003c= 7.1.0"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
