Antonio MoralesDisclosure policy
Last updated: April 9th, 2019
The GitHub Security Lab research team is dedicated to working closely with the open source community and with projects that are affected by a vulnerability, in order to protect users and ensure a coordinated disclosure. When we identify a vulnerability in a project, we will report it by contacting the publicly-listed security contact for the project if one exists; otherwise we will attempt to contact the project maintainers directly.
If the project team responds and agrees the issue poses a security risk, we will work with the project security team or maintainers to communicate the vulnerability in detail, and agree on the process for public disclosure. Responsibility for developing and releasing a patch lies firmly with the project team, though we aim to facilitate this by providing detailed information about the vulnerability.
Our disclosure deadline for publicly disclosing a vulnerability is: 90 days after the first report to the project team.
We appreciate the hard work maintainers put into fixing vulnerabilities and understand that sometimes more time is required to properly address an issue. We want project maintainers to succeed and because of that we are always open to discuss our disclosure policy to fit your specific requirements, when warranted.
Please contact us at securitylab@github.com if you have any questions about our disclosure policy or our security research.
