Prior to 1.8.8 and 2.2.0, the src/functions.js lookup function lacked an Object.prototype.hasOwnProperty check and allowed crafted expressions to access inherited prototype members. An attacker able to supply an expression could use inherited prototype setters and getters, constructor access, valueOf, and process.getBuiltinModule to reach the child_process module and execute arbitrary code with the privileges of the host process. This issue is fixed in versions 1.8.8 and 2.2.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":null}],"references":["https://github.com/jsonata-js/jsonata/security/advisories/GHSA-8gq3-vp5j-2grp","https://github.com/jsonata-js/jsonata/pull/794","https://github.com/jsonata-js/jsonata/commit/4b217d514376e30cba278941298d7ba97c4a6c6e","https://github.com/jsonata-js/jsonata/commit/4c5f4adfb90a9b500889d50f90050ca68888b50d","https://github.com/jsonata-js/jsonata/releases/tag/v1.8.8","https://github.com/jsonata-js/jsonata/releases/tag/v2.2.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-64155","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Aug 21, 2026, 8:47:08 PM","dateUpdated":"Aug 24, 2026, 7:42:37 PM"},"relatedAdvisories":[{"id":"RHSA-2026:76788","title":"Red Hat Security Advisory: Red Hat Developer Hub 1.10.5 Plugin Catalog GA plugins release.","vulnerabilityIds":["CVE-2026-13697","CVE-2026-19534","CVE-2026-47683","CVE-2026-47686","CVE-2026-47698","CVE-2026-55553","CVE-2026-75899","CVE-2026-75931","CVE-2026-75975","CVE-2026-76172","CVE-2026-77037","CVE-2026-77078","CVE-2026-77413","CVE-2026-77414","CVE-2026-77415","CVE-2026-82333","CVE-2026-82417","CVE-2026-84292","CVE-2026-84375","CVE-2026-84394","CVE-2026-84961","CVE-2026-87776","CVE-2026-88932","CVE-2026-89011","CVE-2026-92934","CVE-2026-92935","CVE-2026-92937","CVE-2026-92938","CVE-2026-92939","CVE-2026-92940","CVE-2026-92941","CVE-2026-92942","CVE-2026-92944","CVE-2026-92946","CVE-2026-92947","CVE-2026-92948","CVE-2026-92950","CVE-2026-92951","CVE-2026-92953","CVE-2026-92954","CVE-2026-92955","CVE-2026-92956","CVE-2026-92957","CVE-2026-92958","CVE-2026-92959","CVE-2026-92960","CVE-2026-92961","CVE-2026-93603","CVE-2026-93604","CVE-2026-93605","CVE-2026-93606"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
