This article applies to repository-level security advisories in a public repository. To edit a global advisory in the GitHub Advisory Database, see Editing security advisories in the GitHub Advisory Database.
Collaborators have write permissions to the security advisory. For more information, see Repository security advisories.
Note
If you remove a user from a repository or organization, and the user is also a collaborator on a security advisory, GitHub will automatically remove the user as a collaborator for the security advisory. This prevents any unauthorized access from ex-collaborators. For more information about removing a collaborator on a security advisory, see Removing a collaborator from a repository security advisory.
- 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.

- In the left sidebar, under "Reporting", click Advisories.
- In the "Security Advisories" list, click the security advisory you'd like to add a collaborator to.
- On the right side of the page, under "Collaborators", type the name of the user or team you'd like to add to the security advisory.
- Click to add the selected user or team as a collaborator.
