LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-18489 confirms this npm version as malicious. @ifasn/mmdd-doc-mcp advertises itself as a Markdown TOC/stats/table MCP server, but on startup (bin entry / \`npm start\`) its index.js performs an unsolicited IMDSv2 handshake against the Alibaba Cloud ECS metadata endpoint 100.100.100.200: a PUT to /latest/api/token with X-aliyun-ecs-metadata-token-ttl-seconds followed by a GET to /latest/meta-data/ram/security-credentials/, retrieving the host instance's RAM... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-11-02T21:19:35.649Z - **Finished:** 2026-11-02T21:20:04.564Z - **Download time:** 507 ms - **Static scan time:** 194 ms - **AI review time:** 28213 ms - **Total time:** 28915 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** A dormant build script can inject metadata and sensitive-path collection into index.js; the shipped entry point does not contain that probe. - **Trigger:** Manual execution of build116.js, followed by running the generated index.js. - **Impact:** If the generated code is run in a cloud or sensitive environment, metadata and some local file contents may be collected into a local dump. No external transmission was found in the inspected probe code. - **Evidence paths:** build116.js, package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T21:20:04.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script constructs code that requests cloud instance metadata and reads selected local paths, then writes collected results to output/meta\_field\_dump.txt. - **Rationale:** The shipped entry point appears limited to Markdown tools, but a bundled build script can inject cloud metadata and sensitive-path collection into it. The script is not an install hook and is not run by the manifest, so this is a dormant but meaningful risk rather than confirmed automatic exfiltration. - **Files touched:** index.js, package.json, output/meta\_field\_dump.txt, /var/lib/kubelet/pods/8993a2c7-960f-48ac-9650-73c4660e75b0/etc-hosts, /etc/hosts, /etc/shadow, /etc/passwd, /var/run/secrets/kubernetes.io/serviceaccount/token, /var/www/html/.env, /root/.ssh/id\_rsa, /var/www/html/config.php - **Network endpoints:** 100.100.100.200 ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** build116.js contains code to query the Alibaba Cloud metadata endpoint and save returned metadata text in a local dump., The same build script targets sensitive local paths, including a Kubernetes service-account token, .env, and SSH private key paths., The manifest has no install lifecycle hooks; it points to index.js as the main and bin entry point., The shipped index.js implements Markdown tools and dispatches their requested calls; it contains no metadata probe call. - **Evidence against:** The metadata and sensitive-path collection are embedded in build116.js, which the manifest does not run automatically., The shipped index.js exposes the Markdown tools and has no reference to the metadata endpoint or metadata probe. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@1.1.6. - Avoid installing @ifasn/mmdd-doc-mcp@1.1.6. 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.
