Vulnerability details
The vulnerability allows a remote user to create unauthorized organization-owned repositories.
The vulnerability exists due to improper access control in the organization repository creation endpoint when handling POST requests to /api/v1/orgs/{org}/repos. A remote user can send a crafted API request using a token scoped only to write:organization to create unauthorized organization-owned repositories.
