Flutter 的安全性说明

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

Reporting vulnerabilities

To report a vulnerability, please e-mail security@flutter.dev with a description of the issue, the steps you took to create the issue, affected versions, and if known, mitigations for the issue.

We should reply within three working days, probably much sooner.

We use GitHub’s security advisory feature to track open security issues. You should expect a close collaboration as we work to resolve the issue you have reported. Please reach out to security@flutter.dev again if you do not receive prompt attention and regular updates.

You may also reach out to the team via our public Discord chat channels; however, please make sure to e-mail security@flutter.dev when reporting an issue, and avoid revealing information about vulnerabilities in public if that could put users at risk.

For more details on how we handle security vulnerabilities, please see our internal processes.

Best practices

  • Keep current with the latest Flutter SDK releases. We regularly update Flutter, and these updates may fix security defects discovered in previous versions. Check the Flutter change log 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 pin accordingly.

  • Keep your copy of Flutter up to date. Private, customized versions of Flutter tend to fall behind the current version and may not include important security fixes and enhancements. Instead, routinely update your copy of Flutter. If you’re making changes to improve Flutter, be sure to update your fork and consider sharing your changes with the community.
