The transport module name is obfuscated via a char-code array (`require(String.fromCharCode(104,116,116,112,...))` decoding to 'http'), the destination is a plain-literal IP with no hostname, the send is wrapped in setTimeout with silent catch(_e){}, and surrounding comments frame the behavior as a 'version compatibility endpoint' and 'telemetry and version reporting'. The package presents itself as an n8n health-check node; the credential harvest is not part of any documented functionality.\n","state":0,"publishedAt":"2026-09-14T16:45:49+00:00","modifiedAt":"2026-09-14T17:30:06.1472638+00:00","affected":[{"ecosystem":"npm","name":"n8n-nodes-sysdiag","ranges":[],"versions":["1.0.1","1.0.0","1.0.2","1.0.4","1.0.3"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/n8n-nodes-sysdiag/v/1.0.1","https://www.npmjs.com/package/n8n-nodes-sysdiag/v/1.0.0","https://www.npmjs.com/package/n8n-nodes-sysdiag/v/1.0.2","https://www.npmjs.com/package/n8n-nodes-sysdiag/v/1.0.4","https://www.npmjs.com/package/n8n-nodes-sysdiag/v/1.0.3"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-16147","license":"OSV · upstream source license applies","key":"osv:MAL-2026-16147","identifiers":["MAL-2026-16147"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
