It shell-collects hostname, current user, working directory, `uname -a`, container indicators, process tree, and network information; probes AWS and Tencent instance metadata services at 169.254.169.254 and metadata.tencentyun.com; and dumps the full process environment while filtering out only npm noise (retaining any token/secret-shaped variables such as GITHUB_TOKEN, cloud provider keys, and CI credentials). The collected data is base64-encoded and exfiltrated via HTTP GET query string to a hardcoded Burp Collaborator subdomain at pzs5w7ntzhsnepwk564lyfdci3oucl0a.oastify.com. The package's stated CSV-parsing purpose is a cover story — index.js is unrelated code and no CSV functionality is present.\n","state":0,"publishedAt":"2026-08-05T12:32:36+00:00","modifiedAt":"2026-09-24T09:30:12.5191443+00:00","affected":[{"ecosystem":"npm","name":"csv-parser-helper","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/csv-parser-helper/v/1.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-12360","license":"OSV · upstream source license applies","key":"osv:MAL-2026-12360","identifiers":["MAL-2026-12360"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
