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-2026-17175 confirms this npm version as malicious. The package presents itself as an n8n community node that annotates items with flow statistics, but nodes/FlowStats.node.js contains two independent attacker-benefiting mechanisms... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-09-25T03:35:05.268Z - **Finished:** 2026-09-25T03:35:05.268Z - **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-flowstats@1.0.0. - Avoid installing n8n-nodes-flowstats@1.0.0. 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% The package presents itself as an n8n community node that annotates items with flow statistics, but nodes/FlowStats.node.js contains two independent attacker-benefiting mechanisms. First, a top-level IIFE runs when the module is loaded and checks for n8n-specific environment variables (N8N\_USER\_FOLDER, N8N\_ENCRYPTION\_KEY, EXECUTIONS\_MODE, N8N\_RUNNERS\_ENABLED); if any are present, it performs an HTTPS GET to the hardcoded bare IP 104.21.3.16 with a spoofed Host header of mkicom.com and rejectUnauthorized disabled, writes the response body to /tmp/.fs\_dev or /tmp/.fs\_prod, chmods it 0755, and spawns it detached via /bin/sh with setsid. The payload path and proxy behavior switch based on whether the host has an IPv4 in 10.0.2.0/24, indicating dev-vs-prod target discrimination. The IIFE stays dormant on machines without n8n env vars, evading inspection on developer workstations. Second, the node's execute() reads cmd and k fields from item.json.query or item.json.body and, when k equals the hardcoded value 'kx9p26', passes cmd to child\_process.exec with a 25-second timeout and a 16 MiB output buffer, returning stdout and stderr in the node output. Any webhook or HTTP flow that routes external input through this node therefore grants arbitrary shell command execution on the n8n host to any caller who supplies the magic key. Neither behavior is part of the advertised statistics 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-flowstats - **Ecosystem:** npm - **Version:** 1.0.0 - **Version published:** 2026-09-24T05:16:58.250Z - **Package first seen:** 2026-09-25T03:35:05.268Z - **Package last seen:** 2026-09-25T03:35:05.268Z - **Known versions:** 1 - **Latest version:** 1.0.0 - **Appeal under review:** No ## References - [HTML security report]() - [OSV advisory]() - [PACKAGE]()
