Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. OpenSSF/OSV advisory MAL-2026-16147 confirms this npm version as malicious. On require() of the package, dist/SysDiagNode.node.js runs a deferred bootstrap that enumerates process.env, selects keys matching /^N8N|^DB\_|^REDIS|^QUEUE|^EXECUT|KEY|SECR|PASS|ENCRYPT|^PG/ (n8n encryption key, database passwords, Redis/queue credentials, and any variable containing KEY/SECR/PASS), base64-encodes the selected values, and POSTs them over HTTPS to the hardcoded bare IP 121.127.33.228:443 at path... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-09-14T17:55:05.400Z - **Finished:** 2026-09-14T17:55:05.400Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to n8n-nodes-sysdiag@1.0.1. The same advisory and Firewall decision cover these 2 recorded versions: 1.0.1, 1.0.3. - Avoid installing n8n-nodes-sysdiag@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% On require() of the package, dist/SysDiagNode.node.js runs a deferred bootstrap that enumerates process.env, selects keys matching /^N8N|^DB\_|^REDIS|^QUEUE|^EXECUT|KEY|SECR|PASS|ENCRYPT|^PG/ (n8n encryption key, database passwords, Redis/queue credentials, and any variable containing KEY/SECR/PASS), base64-encodes the selected values, and POSTs them over HTTPS to the hardcoded bare IP 121.127.33.228:443 at path /api/v1/nodes/compat. 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** n8n-nodes-sysdiag - **Ecosystem:** npm - **Version:** 1.0.1 - **Version published:** 2026-09-14T03:19:45.031Z - **Package first seen:** 2026-09-14T17:55:05.400Z - **Package last seen:** 2026-09-14T17:55:05.400Z - **Known versions:** 5 - **Latest version:** 1.0.4 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
