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":"2026-08-21T21:17:07.267+00:00","modifiedAt":"2026-10-12T16:10:00.22+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · security-advisories@github.com · Secondary","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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":9.3,"severity":"CRITICAL"}],"references":["https://github.com/jsonata-js/jsonata/commit/4b217d514376e30cba278941298d7ba97c4a6c6e","https://github.com/jsonata-js/jsonata/commit/4c5f4adfb90a9b500889d50f90050ca68888b50d","https://github.com/jsonata-js/jsonata/pull/794","https://github.com/jsonata-js/jsonata/releases/tag/v1.8.8","https://github.com/jsonata-js/jsonata/releases/tag/v2.2.0","https://github.com/jsonata-js/jsonata/security/advisories/GHSA-8gq3-vp5j-2grp"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77413","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-94"],"productCriteria":[],"sourceDates":{"published":"2026-08-21T21:17:07.267","lastModified":"2026-10-12T16:10:00.220"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
