Hardcoded Axiom ingest token (AXIOM_INGEST_TOKEN) shipped in the published npm package

Summary

The published react-doctor npm package ships a hardcoded Axiom ingest token (AXIOM_INGEST_TOKEN) inside its dist bundle. Telemetry is enabled by default, so the CLI uses this static token as the Authorization: Bearer credential for first-party Axiom OTLP traces/metrics export. Because the token is bundled into the published tarball, anyone can extract it and use it to write arbitrary data into the two first-party telemetry datasets or consume the ingest write quota.

Root cause

1. packages/react-doctor/src/cli/utils/constants.ts:212 (still present on main as of commit 1971506440):

   typescript复制

   export const AXIOM_INGEST_TOKEN = "xaat-31b5…459ce";

2. packages/react-doctor/src/cli/utils/resolve-axiom-telemetry-options.ts:28 — used as the default credential whenever the env override is unset:

   typescript复制

   const token = process.env.REACT_DOCTOR_AXIOM_TOKEN || AXIOM_INGEST_TOKEN;

3. packages/core/src/observability.ts:102-103 (buildAuthorization) emits Bearer ${Redacted.value(options.token)} on the Axiom OTLP export requests (used at lines 120 and 143).

4. packages/react-doctor/package.json → "files": ["bin/**", "dist/**/*.js", "dist/**/*.d.ts", …] — the token-bearing compiled output is published to npm ([email protected], the current latest release).

Telemetry is on by default: isTelemetryEnabled() returns true unless --no-telemetry / --no-score is passed, REACT_DOCTOR_NO_TELEMETRY is set, or the process runs under a test environment.

Impact

The token is scoped ingest:create to exactly two datasets and carries no read or organization permissions (as documented in the constants.ts comment). A public extractor can, at minimum:

• write forged/poisoned traces & metrics into the two first-party datasets, degrading the quality of the project's own telemetry; and
• consume the shared ingest write quota, potentially throttling or blocking legitimate ingest.

It does not expose other users' data or the project's infrastructure beyond those two write-only datasets.

Note

The comment above AXIOM_INGEST_TOKEN already documents that this token ships inside the published tarball, is extractable, and that rotation requires a release — with the standing alternative being to proxy ingest through www.react.doctor so the token stops shipping entirely. This issue is to track that remediation and ask whether the trade-off can be removed, rather than to report an unexpected secret.

Suggested remediation

• Rotate the current token — it has been publicly extractable since it shipped.
• Prefer not shipping a usable ingest credential at all: proxy first-party ingest through www.react.doctor, as the code comment proposes.
• Alternatively, make first-party telemetry opt-in and issue a per-install credential instead of a static bundled one.
• Consider a CI/secret-scan check that fails if a new token literal is added to src/cli/utils/constants.ts.

Verification scope

• Repository: millionco/react-doctor, main branch, token confirmed present at commit 1971506440 (2026-08-17).
• Package: [email protected] publishes dist/**/*.js.
• Chain verified from the checked-out source: constants.ts → resolve-axiom-telemetry-options.ts → core/src/observability.ts (Authorization: Bearer on Axiom OTLP export).
