An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-27307 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- jsonata (npm): affected from 1.4.0; fixed in 1.8.7\n- jsonata (npm): affected from 1.4.0; fixed in 1.8.7\n- jsonata (npm): affected from 2.0.0; fixed in 2.0.4\n- jsonata (npm): affected from 2.0.0; fixed in 2.0.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2024-27307/ (Markdown: https://insights.sbomify.com/CVE-2024-27307/index.md)","id":"CVE-2024-27307","markdown":"https://insights.sbomify.com/CVE-2024-27307/index.md","name":"CVE-2024-27307","record":{"aliases":["GHSA-fqg8-vfv7-8fj8"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"JSONata query library","requires_auth":"none","summary":"Attackers can inject malicious JSONata expressions to pollute the Object prototype, potentially causing remote code execution or denial of service.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"jsonata","vendor":"jsonata"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"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.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"JSONata expression can pollute the \"Object\" prototype","id":"CVE-2024-27307","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"code_injection","year":"2024"},"n_packages":4,"n_references":5,"next":{"headline":"Mio's tokens for named pipes may be delivered after deregistration","id":"CVE-2024-27308"},"packages":[{"ecosystem":"npm","fixed":["1.8.7"],"introduced":["1.4.0"],"last_affected":[],"package":"jsonata","purl":null,"source":"GHSA-fqg8-vfv7-8fj8"},{"ecosystem":"npm","fixed":["1.8.7"],"introduced":["1.4.0"],"last_affected":[],"package":"jsonata","purl":"pkg:npm/jsonata","source":"GHSA-fqg8-vfv7-8fj8"},{"ecosystem":"npm","fixed":["2.0.4"],"introduced":["2.0.0"],"last_affected":[],"package":"jsonata","purl":null,"source":"GHSA-fqg8-vfv7-8fj8"},{"ecosystem":"npm","fixed":["2.0.4"],"introduced":["2.0.0"],"last_affected":[],"package":"jsonata","purl":"pkg:npm/jsonata","source":"GHSA-fqg8-vfv7-8fj8"}],"prev":{"headline":"aiohttp vulnerable to XSS on index pages for static file handling","id":"CVE-2024-27306"},"products":["jsonata"],"published":"2024-03-06","related":[{"cvss_score":7.5,"headline":"JSONata: Malicious inputs to \"$toMillis\" function can cause resource exhaustion","id":"CVE-2026-52746","kev_date_added":null,"published":"2026-07-17"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-13","vendors":["jsonata-js"]},"summary":"Attackers can inject malicious JSONata expressions to pollute the Object prototype, potentially causing remote code execution or denial of service.","url":"https://insights.sbomify.com/CVE-2024-27307/"}
