There has been some confusion over today's security vulnerability and our policy on responsible disclosure and account suspension that I'd like to clear up.

Three days ago, user @homakov opened an issue on rails/rails about the prevalence of the mass-assignment vulnerability. Two days ago he responsibly disclosed a security vulnerability to us and we worked with him to fix it in a timely fashion. Today, he found and exploited the public key form update vulnerability without responsible disclosure. For this reason we temporarily suspended his account for violation of section A8 of the GitHub Terms of Service pending a full investigation into what happened. Now that we've had a chance to review his activity, and have determined that no malicious intent was present, @homakov's account has been reinstated.

We haven't been as clear as we should have been on how to responsibly disclose security problems, and for that I'm sorry. To prevent future confusion about security-related account suspension, and to make explicit our stance on responsible disclosure, we have added a section entitled Responsible Disclosure of Security Vulnerabilities to our Security policy.

By working together we can make the development community safe and productive for everyone. Thank you for your support, and to all those that have helped us keep GitHub safe and secure.
