安全

The Dart team takes the security of Dart and the applications created with it seriously. This page describes how to report any vulnerabilities that you find, and lists best practices to minimize the risk of introducing a vulnerability.

Security philosophy

Dart’s security strategy is based on five key pillars:

  • Identify: Track & prioritize key security risks by identifying core assets, key threats and vulnerabilities.
  • Detect: Detect and identify vulnerabilities using techniques and tools like vulnerability scanning, static application security testing and fuzzing.
  • Protect: Eliminate risks by mitigating known vulnerabilities and protect critical assets against source threats.
  • Respond: Define processes to report, triage and respond to vulnerabilities or attacks.
  • Recover: Build capabilities to contain and recover from an incident with minimal impact.

Reporting vulnerabilities

To report a security issue, use https://g.co/vulnz. Coordination and disclosure happen in the dart-lang GitHub repos (including GitHub security advisories). Please include a detailed description of the issue, the steps you took to create the issue, affected versions, and any mitigations for the issue. The Google Security Team will respond within 5 working days of your report on g.co/vulnz.

For more information about how Google handles security issues, see Google’s security philosophy.

If you believe that an existing issue is security-related, we ask that you report it via https://g.co/vulnz and include the issue id in your report.

Supported versions

We commit to publishing security updates for the version of Dart currently for the most recent stable Dart release.

Expectations

We treat security issues equivalent to a P0 priority level and release a beta or patch fix for any major security issues found in the most recent stable release of the Dart SDK. Any vulnerability reported for Dart websites like dart.dev does not require a release and will be fixed in the website itself.

Dart does not have a bug bounty program.

Receiving security updates

Depending on the issue and the fix release, an announcement will be made to dart-announce mailing list.

Best practices

  • Keep current with the latest Dart SDK releases. We regularly update Dart, and these updates may fix security defects discovered in previous versions. Check the Dart changelog for security-related updates.

  • Keep your application’s dependencies up to date. Make sure you upgrade your package dependencies to keep the dependencies up to date. Avoid pinning to specific versions for your dependencies and, if you do, make sure you check periodically to see if your dependencies have had security updates, and update the version pin accordingly.
