{"id":"CVE-2024-27307","summary":"JSONata expression can pollute the \"Object\" prototype","details":"JSONata is a JSON query and transformation language. Starting in version 1.4.0 and prior to version 1.8.7 and 2.0.4, a malicious expression can use the transform operator to override properties on the `Object` constructor and prototype. This may lead to denial of service, remote code execution or other unexpected behavior in applications that evaluate user-provided JSONata expressions. This issue has been fixed in JSONata versions 1.8.7 and 2.0.4. Applications that evaluate user-provided expressions should update ASAP to prevent exploitation. As a workaround, one may apply the patch manually.","aliases":["GHSA-fqg8-vfv7-8fj8"],"modified":"2026-08-12T03:51:16.254860627Z","published":"2024-03-06T19:24:16.876Z","related":["CGA-v66c-v7w2-xc7p"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27307.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-1321"]},"references":[{"type":"WEB","url":"https://github.com/jsonata-js/jsonata/releases/tag/v2.0.4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/27xxx/CVE-2024-27307.json"},{"type":"ADVISORY","url":"https://github.com/jsonata-js/jsonata/security/advisories/GHSA-fqg8-vfv7-8fj8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-27307"},{"type":"FIX","url":"https://github.com/jsonata-js/jsonata/commit/1d579dbe99c19fbe509f5ba2c6db7959b0d456d1"},{"type":"FIX","url":"https://github.com/jsonata-js/jsonata/commit/335d38f6278e96c908b24183f1c9c90afc8ae00c"},{"type":"FIX","url":"https://github.com/jsonata-js/jsonata/commit/c907b5e517bb718015fcbd993d742ba6202f2be2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jsonata-js/jsonata","events":[{"introduced":"0"},{"fixed":"220b45ab937fd97f2b1a9825b83eeb95c0c6d0b7"},{"introduced":"99717d99a5417c2bb9248eb7e6bde531e3642b4c"},{"fixed":"57314161b6bd95c9806d723016e9749af2179049"},{"fixed":"1d579dbe99c19fbe509f5ba2c6db7959b0d456d1"},{"fixed":"335d38f6278e96c908b24183f1c9c90afc8ae00c"},{"fixed":"c907b5e517bb718015fcbd993d742ba6202f2be2"}],"database_specific":{"extracted_events":[{"introduced":"1.4.0"},{"fixed":"1.8.7"},{"introduced":"2.0.0"},{"fixed":"2.0.4"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:jsonata:jsonata:*:*:*:*:*:*:*:*"}}],"versions":["v1.8.6","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.0","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5","v1.4.1","v1.4","v1.3.3","v1.3.2","v1.3.1","v1.3","v1.2.6","v1.2.5","v1.2.4","v1.2.2","v1.2.1","v1.2","v1.1.1","v1.1","v1.0.10","v1.0.9","v1.0.8","v1.0.7","v1.0.6","v1.0.5","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-27307.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
