A separate beacon labeled 'rce-poc-v3' sends Node.js version, platform, and PID to the same host. child_process is acquired both directly and via a fallback that instantiates a new Module (new module.constructor()) and copies module.paths — an evasion technique to bypass simple require('child_process') scans. The package name resembles a generic accessibility helper, but the shipped registry entry performs host identity, network configuration, user, and environment-variable harvesting with no legitimate purpose.\n","state":0,"publishedAt":"2026-10-04T23:28:48+00:00","modifiedAt":"2026-10-04T23:45:16.9813645+00:00","affected":[{"ecosystem":"npm","name":"a11y-tabindex-manager","ranges":[],"versions":["1.0.0"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/a11y-tabindex-manager/v/1.0.0"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17501","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17501","identifiers":["MAL-2026-17501"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
