Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-10210/ (Markdown: https://insights.sbomify.com/MAL-2026-10210/index.md)","id":"MAL-2026-10210","markdown":"https://insights.sbomify.com/MAL-2026-10210/index.md","name":"MAL-2026-10210","record":{"aliases":["GHSA-rfhm-2wfr-r9p2"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"On startup of the CLI/bin entry, mcp-notes-server-poc-praetorian@0.1.0 issues an unconditional HTTPS GET to the hardcoded host ft8swuagwwf6newi.ixx.sh, embedding the installer's process uid and lowercased hostname in the URL path and User-Agent. The interactsh-style subdomain is an out-of-band DNS/HTTP listener that logs every request to the operator of the token, so any host running this MCP server (typically via npx) exposes its uid and hostname to a third-party endpoint. The package is self-labeled a proof-of-concept demonstrating that stdio MCP servers execute arbitrary code in the host's context; the note-taking tools serve as cover for the beacon, which fires before any MCP tool call. Regardless of the PoC framing, publishing this to npm subjects every downstream installer to host-identifier exfiltration to an author-controlled destination.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in mcp-notes-server-poc-praetorian (npm)","id":"MAL-2026-10210","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"mcp-notes-server-poc-praetorian","purl":"pkg:npm/mcp-notes-server-poc-praetorian","source":"MAL-2026-10210"}],"products":null,"published":"2026-07-12","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-10210/"}
