snyk library and cli utility
AI Security Review
scanned 6h ago · by lpm-firewall-aiThe postinstall hook reports bootstrap errors and their stacks to Snyk’s Sentry service by default, with an environment-variable opt-out. The inspected report path does not include credentials or project data, so this is suspicious install-time telemetry rather than malicious exfiltration.
Static reason
One or more suspicious static signals were detected.
Trigger
The postinstall bootstrap encounters an error, such as a failed CLI download.
Impact
Install failure details and stack information may be sent to Snyk’s Sentry service. The inspected code does not show credentials or project data being sent.
Mechanism
The bootstrap calls logError, which captures an error message and stack with Sentry when analytics is enabled; analytics is on by default.
AI rationale
The postinstall hook reports bootstrap errors and their stacks to Snyk’s Sentry service by default, with an environment-variable opt-out. The inspected report path does not include credentials or project data, so this is suspicious install-time telemetry rather than malicious exfiltration.

Decision evidence
public snapshotAI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall script runs wrapper_dist/bootstrap.js with the exec argument.
- If the install bootstrap fails, it calls common.logError with the error.
- logError sends the error message and stack to the configured Sentry endpoint when analytics is enabled.
- Analytics is enabled by default; two environment variables can disable it.
- The bootstrap downloads the CLI from Snyk release hosts and checks the downloaded file against a packaged SHA-256 value.
Evidence against
- The reported telemetry is limited in the inspected code to install failures; no credentials, project files, or environment values are included in the reported error.
- The download hosts belong to Snyk, and the wrapper checks the binary checksum before accepting it.
