Prior to 10.25.4, the sort_natural filter bypasses the ownPropertyOnly security option, allowing template authors to extract values of prototype-inherited properties through a sorting side-channel attack. Applications relying on ownPropertyOnly: true as a security boundary (e.g., multi-tenant template systems) are exposed to information disclosure of sensitive prototype properties such as API keys and tokens. This vulnerability is fixed in 10.25.4.","published_at":"2026-04-08T19:39:17.780000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-200"],"nvd_references":["https://github.com/harttle/liquidjs/security/advisories/GHSA-rv5g-f82m-qrvv","https://github.com/harttle/liquidjs/pull/869","https://github.com/harttle/liquidjs/commit/e743da0020d34e2ee547e1cc1a86b58377ebe1ce","https://github.com/harttle/liquidjs/releases/tag/v10.25.4"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:07.988593Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"harttle","vendor_name":"harttle","product_slug":"liquidjs","product_name":"liquidjs","version_start":"< 10.25.4","version_start_inclusive":true,"version_end":"< 10.25.4","version_end_inclusive":true,"cpe23_uri":"cve5:harttle:liquidjs:< 10.25.4:< 10.25.4"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/harttle/liquidjs/security/advisories/GHSA-rv5g-f82m-qrvv","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/harttle/liquidjs/pull/869","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/harttle/liquidjs/commit/e743da0020d34e2ee547e1cc1a86b58377ebe1ce","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/harttle/liquidjs/releases/tag/v10.25.4","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-04-08T19:39:17.780000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:53:39.415886Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:39.415886Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:53:39.415886Z","label":"CVSS score revised","source":"cvelistv5"}]}
