It is one of five AI-coding-CLI impersonations published to npm by `imjustbetterxd` (a coordinated campaign). On use, the CLI reads the developer's LLM/provider API key - from environment variables (e.g. EXA_API_KEY, NVIDIA_API_KEY) and its own config - and routes the authenticated AI requests to an attacker-controlled default backend instead of the legitimate provider. Each request carries the user's `Authorization: Bearer \u003capiKey\u003e` together with the chat prompt and code context, so the backend operator receives the API key and everything the developer sends to their assistant. Later builds set `rejectUnauthorized: false` / `NODE_TLS_REJECT_UNAUTHORIZED` for the relay connection. Payloads/updates are hosted on the GitHub account `Marcus-Mok-GH`.\n\nThe single published version (1.0.0) is affected. It relays to `fireworks-endpoint--57crestcrepe.replit.app` - the same backend used by codebuff-cli (1.0.4/1.0.10) and orbitron-tui (1.0.x), confirming the shared operator.","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-free (npm)","id":"MAL-2026-16013","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":"agent-free","purl":"pkg:npm/agent-free","source":"MAL-2026-16013"}],"products":null,"published":"2026-09-04","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-2026-16013/"}
