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.

Additionally, src/index.js's exported init()/check()/wrap() API falls back to the same hardcoded DSN when neither options.dsn nor process.env.SENTRY_DSN is set and enables sendDefaultPii: true, so consumers following the README route their application's exception data (including PII such as IP addresses) to the author's Sentry project by default.\n\nAny computer that has this package installed or running should be considered fully compromised.
