{"id":"CVE-2026-39859","summary":"LiquidJS has a renderFile() / parseFile() bypass configured root and allow arbitrary file read","details":"LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.25.3, liquidjs 10.25.0 documents root as constraining filenames passed to renderFile() and parseFile(), but top-level file loads do not enforce that boundary. A Liquid instance configured with an empty temporary directory as root can return the contents of arbitrary files. This vulnerability is fixed in 10.25.3.","aliases":["GHSA-v273-448j-v4qj"],"modified":"2026-07-27T03:56:44.414153194Z","published":"2026-04-08T19:45:21.747Z","related":["CGA-mgr8-hrmg-6fg9"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39859.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/39xxx/CVE-2026-39859.json"},{"type":"ADVISORY","url":"https://github.com/harttle/liquidjs/security/advisories/GHSA-v273-448j-v4qj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-39859"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/harttle/liquidjs","events":[{"introduced":"0"},{"fixed":"8f69a0839903d85c7b5c9097e39ecce6ac3eab05"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"10.25.3"}],"source":["AFFECTED_FIELD","CPE_RANGE"],"cpe":"cpe:2.3:a:liquidjs:liquidjs:*:*:*:*:*:node.js:*:*"}}],"versions":["v10.25.2","v10.25.1","v10.25.0","v10.24.0","v10.23.0","v10.22.0","v10.21.1","v10.21.0","v10.20.3","v10.20.2","v10.20.1","v10.20.0","v10.19.1","v10.19.0","v10.18.0","v10.17.0","v10.16.7","v10.16.6","v10.16.5","v10.16.4","v10.16.3","v10.16.2","v10.16.1","v10.16.0","v10.15.0","v10.14.0","v10.13.1","v10.13.0","v10.12.0","v10.11.1","v10.11.0","v10.10.2","v10.10.1","v10.10.0","v10.9.4","v10.9.3","v10.9.2","v10.9.1","v10.9.0","v10.8.4","v10.8.3","v10.8.2","v10.8.1","v10.8.0","v10.7.1","v10.7.0","v10.6.2","v10.6.1","v10.6.0","v10.5.0","v10.4.0","v10.3.3","v10.3.2","v10.3.1","v10.3.0","v10.2.0","v10.1.0","v10.0.0","v9.43.0","v9.42.1","v9.42.0","v9.41.0","v9.40.0","v9.39.2","v9.39.1","v9.39.0","v9.38.0","v9.37.0","v9.36.2","v9.36.1","v9.36.0","v9.35.2","v9.35.1","v9.35.0","v9.34.1","v9.34.0","v9.33.1","v9.33.0","v9.32.1","v9.32.0","v9.31.0","v9.30.0","v9.29.0","v9.28.6","v9.28.5","v9.28.4","v9.28.3","v9.28.2","v9.28.1","v9.28.0","v9.27.1","v9.27.0","v9.26.0","v9.25.1","v9.25.0","v9.24.2","v9.24.1","v9.24.0","v9.23.4","v9.23.3","v9.23.2","v9.23.1","v9.23.0","v9.22.1","v9.22.0","v9.21.0","v9.20.1","v9.20.0","v9.19.0","v9.18.0","v9.17.0","v9.16.1","v9.16.0","v9.15.1","v9.15.0","v9.14.1","v9.14.0","v9.13.0","v9.12.0","v9.11.11","v9.11.10","v9.11.9","v9.11.8","v9.11.7","v9.11.6","v9.11.5","v9.11.4","v9.11.3","v9.11.2","v9.11.1","v9.11.0","v9.10.0","v9.9.0","v9.8.0","v9.7.2","v9.7.1","v9.7.0","v9.6.2","v9.6.1","v9.6.0","v9.5.0","v9.4.2","v9.4.1","v9.4.0","v9.3.1","v9.3.0","v9.2.0","v9.1.1","v9.1.0","v9.0.1","v9.0.0","v8.5.3","v8.5.2","v8.5.1","v8.5.0","v8.4.1","v8.4.0","v8.3.0","v8.2.4","v8.2.3","v8.2.2","v8.2.1","v8.2.0","v8.1.0","v8.0.3","v8.0.2","v8.0.1","v8.0.0","v7.5.1","v7.5.0","v7.4.0","v7.3.1","v7.3.0","v7.2.2","v7.2.1","v7.2.0","v7.1.0","v7.0.2","v7.0.1","v7.0.0","v6.4.3","v6.4.2","v6.4.1","v6.4.0","v6.3.1","v6.3.0","v6.2.1","v6.2.0","v6.1.1","v6.0.1","v6.0.0","v5.3.0-0","v5.2.0","v5.1.1","v5.1.0","v5.0.2","v5.0.1","v5.0.0","v4.0.0","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.0","v2.2.1","v2.2.0","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.0","v1.7.9","v1.7.8","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.3","v1.4.2","v1.4.1","v1.3.3","v1.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-39859.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
