Owners and administrators of public repositories can enable private vulnerability reporting on their repositories. For more information, see Configuring private vulnerability reporting for a repository.
Note
- If you have admin or security permissions for a public repository, you don't need to submit a vulnerability report. Instead, you can create a draft security advisory directly. For more information, see Creating a repository security advisory.
- The ability to privately report a vulnerability in a repository is not related to the presence of a
SECURITY.mdfile in that repository's root ordocsdirectory.- The
SECURITY.mdfile contains the security policy for the repository. Repository administrators can add and use this file to provide public instructions for how to report a security vulnerability in their repository. For more information, see Adding a security policy to your repository. - You can only report a vulnerability privately for repositories where private vulnerability reporting is enabled, and you don't have to follow the instructions in the
SECURITY.mdfile. This reporting process is fully private, and GitHub notifies the repository administrators directly about your submission.

About privately reporting a security vulnerability
Security researchers often feel responsible for alerting users to a vulnerability that could be exploited. If there are no clear instructions about contacting maintainers of the repository containing the vulnerability, security researchers may have no other choice but to post about the vulnerability on social media, send direct messages to the maintainer, or even create public issues. This situation can potentially lead to a public disclosure of the vulnerability details.
Private vulnerability reporting makes it easy for security researchers to report vulnerabilities directly to the repository maintainer using a simple form.
For security researchers, the benefits of using private vulnerability reporting are:
- Less frustration, and less time spent trying to figure out how to contact the maintainer.
- A smoother process for disclosing and discussing vulnerability details.
- The opportunity to discuss vulnerability details privately with the repository maintainer.
Note
If the repository doesn't have private vulnerability reporting enabled, you need to initiate the reporting process by following the instructions in the security policy for the repository, or create an issue asking the maintainers for a preferred security contact. For more information, see About coordinated disclosure of security vulnerabilities.
Privately reporting a security vulnerability
If a public repository has private vulnerability reporting enabled, anyone can privately report a security vulnerability to repository maintainers. Users can also evaluate the general security of a public repository and suggest a security policy. For more information, see Evaluating the security settings of a repository.
-
On GitHub, navigate to the main page of the repository.
-
Under the repository name, click Security. If you cannot see the "Security" tab, select the dropdown menu, and then click Security.
-
Click Report a vulnerability to open the advisory form.
-
Fill in the advisory details form.
Tip
In this form, only the title and description are mandatory. (In the general draft security advisory form, which the repository maintainer initiates, specifying the ecosystem is also required.) However, we recommend security researchers provide as much information as possible on the form so that the maintainers can make an informed decision about the submitted report. You can adopt the template used by our security researchers from the GitHub Security Lab, which is available on the
github/securitylabrepository.For more information about the fields available and guidance on filling in the form, see Creating a repository security advisory and Best practices for writing repository security advisories.
-
At the bottom of the form, click Submit report. GitHub will display a message letting you know that maintainers have been notified and that you have a pending credit for this security advisory.
Tip
When the report is submitted, GitHub automatically adds the reporter of the vulnerability as a collaborator and as a credited user on the proposed advisory.
-
Optionally, click Start a temporary private fork if you want to start to fix the issue. Note that only the repository maintainer can merge changes from that private fork into the parent repository.
The next steps depend on the action taken by the repository maintainer. For more information, see Managing privately reported security vulnerabilities.
