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.

This grants whoever controls the relay endpoint, or anyone holding a session URL, interactive command execution on the host running the agent, including via a `ping`/`GET`/`POST`/`http.request` command path in dist/local-control-client.js, dist/local-control-http.js, dist/tunnel.js, dist/upgrade-operations.js, and worker/worker.cjs. Publisher provenance for the relay is unclear: package.json homepage points at github.com/yilee/agentlink, the README's Related link points at a different GitHub owner (kailunshi_microsoft/AgenticWorker), and the branding plus hardcoded relay domain is msclaude.ai, which is not tied to a verifiable publisher identity. In addition, emergency-upgrade.js fetches a release manifest from https://msclaude.ai/files/agent/latest.json (and beta.json) and downloads a replacement tarball from the same origin, verifying only hash/size/name against a manifest served by that same origin — so control of msclaude.ai also grants signed-by-manifest package replacement.","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 @agent-link/agent (npm)","id":"MAL-2026-10705","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":[],"last_affected":[],"package":"@agent-link/agent","purl":"pkg:npm/%40agent-link/agent","source":"MAL-2026-10705"}],"products":null,"published":"2026-07-16","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-2026-10705/"}
