{"cve":"CVE-2026-106120","nvd":{"published":"2026-10-06T19:17:42.960","modified":"2026-10-09T02:16:57.747","status":"Deferred","description":"LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to 10.27.2, enabling ownPropertyOnly does not consistently restrict inherited array indices because negative indexing, .first, .last, the first filter, the last filter, join, reverse, slice, compact, and for-loop iteration can read prototype-provided elements outside readJSProperty(). An attacker who can influence prototype state or inherited array-index data and cause templates to render affected operations can disclose values that ownPropertyOnly is expected to hide. Direct positive indexing and ordinary object prototype reads are blocked, but the alternate array paths remain affected. This issue is fixed in 10.27.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.0},"cvss_v3":null,"cwes":["CWE-200"],"references":["https://github.com/harttle/liquidjs/commit/552819a84b80c62306fe61072628a756272dc749","https://github.com/harttle/liquidjs/pull/924","https://github.com/harttle/liquidjs/releases/tag/v10.27.2","https://github.com/harttle/liquidjs/security/advisories/GHSA-fwxr-j5w2-587m","https://github.com/harttle/liquidjs/security/advisories/GHSA-fwxr-j5w2-587m"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:01.639778232+00:00"},"epss":{"cve":"CVE-2026-106120","score":0.00409,"percentile":0.34885,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-fwxr-j5w2-587m","url":"https://osv.dev/vulnerability/GHSA-fwxr-j5w2-587m","summary":"LiquidJS: ownPropertyOnly bypass for inherited array indices in first/last/join/reverse/slice/compact, `.first`/`.last`, negative index, and for-loop iteration","modified":"2026-10-07T16:30:04.720886113Z","packages":[{"ecosystem":"npm","name":"liquidjs","purl":"pkg:npm/liquidjs","ranges":["<10.27.2"],"fixed":["10.27.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
