Project: Vitess (App Definition and Development / Database)
File: SECURITY.md

Vitess is a large growing community of volunteers, users, and vendors. The Vitess community has adopted this security disclosure and response policy to ensure we responsibly handle critical issues. Security vulnerabilities should be handled quickly and sometimes privately. The primary goal of this process is to reduce the total time users are vulnerable to publicly known exploits. The Vitess team is responsible for the entire response including internal communication and external disclosure. In the future, we may delegate responsibility to a sub-team as other projects have elected to do so. The Vitess community asks that all suspected vulnerabilities be privately and responsibly disclosed via the . If you know of a publicly disclosed security vulnerability please IMMEDIATELY email so that we may start the patch, release, and communication process. For each reported vulnerability, a member of the maintainers team will volunteer to lead coordination of the fix (Fix Lead), and ensure that it is backported to each supported branch. They will then coordinate with the remainder of the maintainers team to coordinate new releases and ensure a communication plan is in place for vulnerability disclosure. All of the timelines below are suggestions and assume a private disclosure. The Fix Lead drives the schedule using their best judgment based on severity and development time. If the Fix Lead is dealing with a public disclosure all timelines become ASAP (assuming the vulnerability has a CVSS score >= 4; see below). If the fix relies on another upstream project's disclosure timeline, that will adjust the process as well. We will work with the upstream project to fit their timeline and best protect our users. If a security vulnerability affects main, but not a currently supported branch, then the following process will apply: The fix will land in main. A courtesy notice will be posted in #developers on Vitess Slack. If a security vulnerability affects only a stable release which is no longer under active support, then the following process will apply: A fix will not* be issued (exceptions may be made for extreme circumstances) A notice will be posted to Vitess Slack in #general channel identifying the threat, and encouraging users to

If a security vulnerability affects supported branches, then a Fix Lead will be appointed and the full security process as defined below will apply. These steps should be completed within the 1-7 days of Disclosure. The Fix Lead will create a using the [CVSS Calculator](https://www.first.org/cvss/calculator/3.0). The Fix Lead makes the final call on the calculated CVSS; it is better to move quickly than making the CVSS perfect. The Fix Lead will notify the maintainers that work on the fix branch is complete. Maintainers will review the fix branch in a private repo and provide require LGTMs. If the CVSS score is under 4.0 ([a low severity score](https://www.first.org/cvss/specification-document#i5)) the maintainers can decide to slow the release process down in the face of holidays, developer bandwidth and other related circumstances. With the fix development underway, the Fix Lead needs to come up with an overall communication plan for the wider community. This Disclosure process should begin after the Fix Lead has developed a Fix or mitigation so that a realistic timeline can be communicated to users. Disclosure of Forthcoming Fix to Users (Completed within 1-7 days of Disclosure) The Fix Lead will update Vitess Slack informing users that a security vulnerability has been disclosed and that a fix will be made available at YYYY-MM-DD HH:MM UTC in the future via this list. This time is the Release Date. The Fix Lead will include any mitigating steps users can take until a fix is available. The communication to users should be actionable. They should know when to block time to apply patches, understand exact mitigation steps, etc. Disclosure of Fixed Vulnerability The Fix Lead will post a notice on Vitess Slack informing users that there are new releases available to address an identified vulnerability. As much as possible this notice should be actionable and include links to CVEs, and how to apply the fix to user's environments; this can include links to external distributor documentation. The Vitess team currently does not provide advance notice of undisclosed vulnerabilities to any third parties. We are open to feedback on what such a policy can or should look like. For the interim, the best way to receive advanced notice of undisclosed vulnerabilities is to apply to join the maintainers team.
