Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. 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. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-10921/ (Markdown: https://insights.sbomify.com/MAL-2026-10921/index.md)","id":"MAL-2026-10921","markdown":"https://insights.sbomify.com/MAL-2026-10921/index.md","name":"MAL-2026-10921","record":{"aliases":["GHSA-qg52-c79f-3q5c"],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"The package's `preinstall` script executes `node examples/verify.js`, which initializes Sentry against a hardcoded author-controlled DSN at `o4510485815754752.ingest.us.sentry.io/4511632673275909` with `sendDefaultPii: true`, resolves the installer's public IP via `https://www.cloudflare.com/cdn-cgi/trace`, and deliberately triggers a captured exception so Sentry ships an event carrying the installer's public IP, `server_name`, username, and other default PII to the author's project on `npm install`. The library entry `src/index.js` additionally hardcodes the same DSN as `DEFAULT_DSN`, so consumers who call `init()` without providing `options.dsn` or `SENTRY_DSN` silently forward their application error events (which routinely contain stack frames, request data, environment values, and user identifiers) to the same author-owned endpoint. Package metadata is generic (name `iot-kfh-s3` unrelated to the described Sentry-wrapper purpose, two-line README stub), inconsistent with a legitimate maintained telemetry library.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
