An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-57350 exists.\n\nAffected packages and fixed versions:\n- csvtojson (npm): affected all versions; fixed in 2.0.13\n- csvtojson (npm): affected all versions; fixed in 2.0.13\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-2025-57350/ (Markdown: https://insights.sbomify.com/CVE-2025-57350/index.md)","id":"CVE-2025-57350","markdown":"https://insights.sbomify.com/CVE-2025-57350/index.md","name":"CVE-2025-57350","record":{"aliases":["CLEANSTART-2026-MC89115","CLSA-2026-1780620677","GHSA-vrw9-g62v-7fmf"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","other"],"network_reachable":"yes","non_default_config":false,"product_category":"Node.js CSV parser","requires_auth":"none","summary":"Prototype pollution in csvtojson allows attackers to cause denial of service or unexpected behavior via malicious CSV headers.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"csvtojson","vendor":"keyangxiang"}],"cvss":{"score":8.6,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"The csvtojson package, a tool for converting CSV data to JSON with customizable parsing capabilities, contains a prototype pollution vulnerability in versions prior to 2.0.10. This issue arises due to insufficient sanitization of nested header names during the parsing process in the parser_jsonarray component. When processing CSV input containing specially crafted header fields that reference prototype chains (e.g., using __proto__ syntax), the application may unintentionally modify properties of the base Object prototype. This vulnerability can lead to denial of service conditions or unexpected behavior in applications relying on unmodified prototype chains, particularly when untrusted CSV data is processed. The flaw does not require user interaction beyond providing a maliciously constructed CSV file.","ecosystems":["npm"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"CSVTOJSON has a prototype pollution vulnerability","id":"CVE-2025-57350","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"npm","product":null,"products":[],"type":"other","year":"2025"},"n_packages":2,"n_references":2,"next":{"headline":"ts-fns has prototype pollution vulnerability","id":"CVE-2025-57351"},"packages":[{"ecosystem":"npm","fixed":["2.0.13"],"introduced":["0"],"last_affected":[],"package":"csvtojson","purl":null,"source":"GHSA-vrw9-g62v-7fmf"},{"ecosystem":"npm","fixed":["2.0.13"],"introduced":["0"],"last_affected":[],"package":"csvtojson","purl":"pkg:npm/csvtojson","source":"GHSA-vrw9-g62v-7fmf"}],"prev":{"headline":"messageformat has a prototype pollution vulnerability","id":"CVE-2025-57349"},"products":["n/a"],"published":"2025-09-24","related":[],"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":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-09-24","vendors":["n/a"]},"summary":"Prototype pollution in csvtojson allows attackers to cause denial of service or unexpected behavior via malicious CSV headers.","url":"https://insights.sbomify.com/CVE-2025-57350/"}
