LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 1.0.3 - **Selected version is latest:** No - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-18489 identifies this version as malicious and supplies the Firewall block. 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:** 91.0% - **Started:** 2026-11-02T21:19:40.108Z - **Finished:** 2026-11-02T21:20:04.564Z - **Download time:** 510 ms - **Static scan time:** 25 ms - **AI review time:** 23920 ms - **Total time:** 24456 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:** The server probes cloud instance metadata automatically and saves successful responses locally. - **Trigger:** Every server startup, through the top-level configSync() call. - **Impact:** May expose cloud environment details in a local file without an explicit user request; no onward transmission is shown in the inspected code. - **Evidence paths:** index.js, output/meta\_field\_dump.txt - **Review source:** ai\_review - **Reviewed:** 2026-11-02T21:20:04.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It makes GET requests to http://100.100.100.200/latest/meta-data/ for a list of metadata paths, then writes successful response text to output/meta\_field\_dump.txt. - **Rationale:** The automatic cloud metadata enumeration and local dump are unrelated to the package’s stated Markdown tools and occur without an explicit request. The inspected code does not send the results to another host, so this warrants a warning rather than a malicious verdict. - **Files touched:** output/meta\_field\_dump.txt - **Network endpoints:** http://100.100.100.200/latest/meta-data/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** The package describes itself as a Markdown document toolkit for TOC generation, word counts, and table formatting., At startup, it automatically requests multiple paths under the cloud metadata endpoint and captures successful responses., It writes the captured metadata responses to output/meta\_field\_dump.txt., The included dump shows the metadata requests timing out. - **Evidence against:** The inspected code sends GET requests only to the link-local metadata endpoint; it shows no onward transmission of the results., package.json declares no install lifecycle scripts. ## Affected versions and remediation This report applies to @ifasn/mmdd-doc-mcp@1.0.3. - Avoid installing @ifasn/mmdd-doc-mcp@1.0.3. 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.
