A `Liquid` instance configured with an empty temporary directory as `root` still returned the contents of `/etc/hosts` when `renderFile('/etc/hosts')` was called. I have not exhaustively checked older releases yet; 10.25.0 is the latest tested version.\n\nRoot cause:\n- `src/parser/parser.ts:83-85` calls `loader.lookup(file, LookupType.Root, ...)` and then reads the returned file.\n- `src/fs/loader.ts:38` passes `type !== LookupType.Root` into `candidates()`.\n- For `LookupType.Root`, `enforceRoot` is false, so `src/fs/loader.ts:47-66` accepts resolved absolute paths and fallback results without any `contains()` check.\n\nThis appears adjacent to the March 10, 2026 fix for CVE-2026-30952, which hardened `include` / `render` / `layout` but not the top-level file-loading APIs.\n\nProof of concept:\n```javascript\nconst fs = require('fs');\nconst os = require('os');\nconst path = require('path');\nconst { Liquid } = require('liquidjs');\n\nconst safeRoot = fs.mkdtempSync(path.join(os.tmpdir(), 'liquidjs-safe-root-'));\nconst engine = new Liquid({ root: [safeRoot], extname: '.liquid' });\n\nengine.renderFile('/etc/hosts').then(console.log);\n```\n\nExpected result: a path outside `root` should be rejected.\nActual result: `/etc/hosts` is rendered successfully.\n\nImpact: any application that treats `root` as a sandbox boundary and forwards attacker-controlled template names into `renderFile()` or `parseFile()` can disclose arbitrary local files readable by the server process.\n\nSuggested fix: apply the same containment checks used for partial/layout lookups to `LookupType.Root`, and reject absolute or fallback paths unless they remain within an allowed root. A regression test should verify that `renderFile('/etc/hosts')` fails when `root` points to an unrelated directory.","state":0,"publishedAt":"2026-04-08T15:04:44+00:00","modifiedAt":"2026-09-10T03:50:44.7976905+00:00","affected":[{"ecosystem":"npm","name":"liquidjs","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"10.25.5"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-v273-448j-v4qj","https://nvd.nist.gov/vuln/detail/CVE-2026-39859","https://github.com/harttle/liquidjs/pull/870","https://github.com/harttle/liquidjs/commit/f41c1fc02fe901598f3328118b42b13bc6bc9b04","https://github.com/harttle/liquidjs","https://github.com/harttle/liquidjs/releases/tag/v10.25.5"],"sourceUrl":"https://github.com/advisories/GHSA-v273-448j-v4qj","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-v273-448j-v4qj","identifiers":["GHSA-v273-448j-v4qj","CVE-2026-39859"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
