High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package's runtime connects to a hardcoded WebSocket relay (default wss://msclaude.ai) and dispatches messages received from that relay directly into a locally spawned PTY. terminal.js spawns the user's default shell (or powershell.exe on Windows) via node-pty and exposes a write() method that pipes network-received bytes straight into the shell (\`ptyProcess?.write(data)\`); connection.js routes \`terminal\_open\` / \`terminal\_input\` events from the WebSocket's \`on('message')\` handler to that PTY. 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** prepublishOnly - **Dependencies:** 11 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 4 - **Published dependency-graph edges:** 11 ### Published dependency entries - @azure/msal-node ^3.8.10 (Dependency) - commander ^12.0.0 (Dependency) - cron-parser ^5.5.0 (Dependency) - js-yaml ^4.1.1 (Dependency) - marked ^17.0.6 (Dependency) - node-cron ^4.2.1 (Dependency) - node-pty ^1.1.0 (Dependency) - qrcode-terminal ^0.12.0 (Dependency) - tweetnacl ^1.0.3 (Dependency) - tweetnacl-util ^0.15.1 (Dependency) - ws ^8.16.0 (Dependency) ## Package metadata - **Package:** @agent-link/agent - **Ecosystem:** npm - **Version:** 0.1.273 - **License:** MIT - **Version published:** 2026-07-17T12:54:18.978Z - **Package first seen:** 2026-07-01T03:06:30.779Z - **Package last seen:** 2026-08-11T14:40:10.651Z - **Known versions:** 48 - **Latest version:** 0.1.330 - **Appeal under review:** No - **Description:** AgentLink local agent CLI - **Maintainers:** kailunshi - **Keywords:** agentlink, claude, claude-code, cli, ai-agent, remote-development - **Runtime engines:** node: \>=18.0.0 - **Artifact files:** 161 - **Artifact unpacked size:** 1,364,927 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Issues]() - [OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
