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-2026-85063 exists.\n\nAffected packages and fixed versions:\n- csv-parse (npm): affected all versions; fixed in 7.0.2\n- csv-parse (npm): affected all versions; fixed in 7.0.2\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-2026-85063/ (Markdown: https://insights.sbomify.com/CVE-2026-85063/index.md)","id":"CVE-2026-85063","markdown":"https://insights.sbomify.com/CVE-2026-85063/index.md","name":"CVE-2026-85063","record":{"aliases":["CLEANSTART-2026-LJ34730","CLEANSTART-2026-OY61738","CLEANSTART-2026-WQ57652","DEBIAN-CVE-2026-85063","ECHO-2240-6ce7-c82e","GHSA-8cw4-87c7-c6xx","MINI-h5vp-4fpq-jqfg","MINI-jfq6-w7ph-3pp7","MINI-vv68-q6rw-5qw4","UBUNTU-CVE-2026-85063"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Node.js CSV parser","requires_auth":"none","summary":"Attackers can exploit prototype pollution in node-csv to inject malicious data and potentially execute code when specific parsing options are enabled.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.9,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-1321","name":"Improperly Controlled Modification of Object Prototype Attributes"}],"description":"node-csv is a full-featured CSV parser with a simple API that is tested against large datasets. Prior to 7.0.2, csv-parse with the columns and group_columns_by_name options enabled treats a duplicate __proto__ header as an existing property in packages/csv-parse/lib/api/index.js, assigns an attacker-controlled array through obj['__proto__'], and replaces the parsed record object's prototype. A malicious CSV header can therefore inject inherited array values into the returned record, hide those inherited values from JSON serialization, and affect property enumeration and type or shape checks in applications that process the record.
