In agent.js, on 'create-session' and 'input' messages the package spawns pty-bridge.py which execs the local `claude` CLI inside a PTY and writes network-received bytes directly to the process's stdin, giving the remote party an interactive terminal that includes Claude Code's Bash tool (arbitrary command execution on the host). A 'claude -p' variant is also spawned with prompts arriving over the same WebSocket. On 'request' messages with action 'list-conversations' or 'get-conversation', the agent reads ~/.claude/projects/*.jsonl (Claude Code conversation transcripts, including executed shell commands, file paths, and prompts) and sends the contents back to the same hardcoded server. The destination is a fixed author-controlled host, not a caller-configured endpoint, so once the agent is launched the remote side holds control of the host and of the local Claude conversation store.","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 claude-remote-agent (npm)","id":"MAL-2026-13376","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":"claude-remote-agent","purl":"pkg:npm/claude-remote-agent","source":"MAL-2026-13376"}],"products":null,"published":"2026-08-05","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-2026-13376/"}
