react-tracked provides state usage tracking with Proxies. Between 2026-05-18 19:26:36 and 2026-05-19 15:22:45, the default branch contained malicious commits 6978272a7d6ca02225cb747ea69f427512e33699 through 949f1a3d6bb1ff7d1a0dec892afd773e742627e8 that executed remote attacker-controlled code on developer machines during . The commits were removed by force-push, but local clones, forks, and direct-SHA URLs may still contain them, and against an affected checkout will still execute the code today. The package was not published to npm. was added and wired into the script. It fetched a JavaScript payload from an attacker-controlled HTTPS endpoint (configurable via an environment variable), disabled TLS verification, and evaluated the response as code with available. Execution was deliberately skipped on CI and cloud/serverless environments, targeting developer workstations. The second-stage payload was attacker-hosted and cannot be reconstructed. Assume full compromise of anything reachable from a Node process with the user's permissions. Those who ran against an affected checkout on a developer machine on or after 2026-05-18 19:26:36 should treat the machine as compromised, rotate every credential the machine could reach, audit account activity** since 2026-05-18 19:26:36, and clean local clones.
