In versions 10.25.7 and below, Context.spawn() creates a child Context for the {% render %} tag but does not propagate the parent context's resolved ownPropertyOnly value, resulting in a silent bypass. The new context re-derives ownPropertyOnly from opts.ownPropertyOnly (the instance-level option), silently discarding any RenderOptions.ownPropertyOnly override that was supplied to parseAndRender(). As a result, a developer who runs a Liquid instance with the backwards-compatible ownPropertyOnly:false and then locks down an untrusted render with parseAndRender(..., { ownPropertyOnly: true }) still leaks prototype-chain properties from inside any {% render %} partial. This is a distinct exploit surface from the previously identified array-filter variants (where, reject, group_by, find, find_index, has) — the underlying root cause in Context.spawn() is shared, but {% render %} is a separately reachable sink that needs no filter usage. This issue has been fixed in version 10.26.0.","state":0,"publishedAt":"2026-06-17T22:25:15.319+00:00","modifiedAt":"2026-06-18T13:53:51.906+00:00","affected":[{"ecosystem":"Vendor product","name":"liquidjs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"harttle\",\n                    \"product\": \"liquidjs\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 10.26.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3,"severity":"MEDIUM"}],"references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-9x9p-qf8f-mvjg","https://github.com/harttle/liquidjs/commit/dbbf6288030591bf6da28d8c1cce5a17bca97bb6","https://github.com/harttle/liquidjs/releases/tag/v10.26.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-44646","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-44646","identifiers":["CVE-2026-44646"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
