OpenSSF/OSV advisory MAL-2026-18486 confirms this npm version as malicious. The package is advertised as a markdown toolkit MCP server (TOC generation, word count, table formatting) but on require() of its main module and on startup of its md-doc-mcp bin it probes cloud-provider instance-metadata services — AWS IMDSv1/v2 (169.254.169.254), GCP, Azure, and Alibaba Cloud (100.100.100.200) — and sends the per-endpoint responses as query-string parameters over plain HTTP to a hardcoded external... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-11-02T21:19:15.366Z - **Finished:** 2026-11-02T21:20:04.564Z - **Download time:** 1272 ms - **Static scan time:** 29 ms - **AI review time:** 47897 ms - **Total time:** 49198 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:** On startup, the entrypoint probes cloud metadata and configuration endpoints, then reports each probe's label and HTTP status to a fixed telemetry host. This is unexplained runtime network reporting unrelated to the Markdown tools; the inspected code discards response bodies. - **Trigger:** Running the package entrypoint. - **Impact:** The remote recipient learns which probes respond, potentially revealing cloud or service presence. No metadata response body or credentials are shown in the reported data. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T21:20:04.564Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint starts configSync, which sends HTTP probes and places their labels and status codes in a telemetry request. - **Rationale:** The CLI entrypoint automatically probes cloud metadata endpoints and reports their status to a fixed external host. Because the source shows no credential or document-content transfer but does not explain this behavior in relation to the Markdown tools, a warning is appropriate. - **Network endpoints:** 100.100.100.200, 169.254.169.254, metadata.google.internal, 121.199.24.94.nip.io, 121.199.24.94 ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** package.json exposes index.js as the command entrypoint and defines a start command that runs it., index.js defines config and cloud metadata endpoints, including AWS and Google metadata services., The request helper discards response bodies and records HTTP status codes., At startup, configSync probes those endpoints and reports their labels and status codes., The report is sent to fixed telemetry hosts., The inspected request data is limited to probe results; the source does not show cloud metadata credentials or document contents being sent. - **Evidence against:** The manifest has no install lifecycle hook., The request helper discards response bodies, and the reported results contain endpoint labels and status codes. ## Affected versions and remediation This report applies to @ifasn/md-doc-mcp@1.0.5. - Avoid installing @ifasn/md-doc-mcp@1.0.5. 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.
