Prior to 0.8.36, the @nyariv/sandboxjs parser contains unbounded recursion in the restOfExp function and the lispify/lispifyExpr call chain. An attacker can crash any Node.js process that parses untrusted input by supplying deeply nested expressions (e.g., ~2000 nested parentheses), causing a RangeError: Maximum call stack size exceeded that terminates the process. This vulnerability is fixed in 0.8.36.","state":0,"publishedAt":"2026-04-06T15:10:42.261+00:00","modifiedAt":"2026-04-07T14:09:53.356+00:00","affected":[{"ecosystem":"Vendor product","name":"SandboxJS","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nyariv\",\n                    \"product\": \"SandboxJS\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 0.8.36\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/nyariv/SandboxJS/security/advisories/GHSA-8pfc-jjgw-6g26"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-34211","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-34211","identifiers":["CVE-2026-34211"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
