### Summary A personal access token restricted with the public-only scope can still retrieve private organization membership and organization permission details for its own account through organization-listing endpoints. This bypass breaks the intended guarantee that such tokens are limited to public resources only. ### Details The issue affects the following endpoints: GET /api/v1/user/orgs GET /api/v1/users/{username}/orgs/{org}/permissions The application correctly prevents a public-only token from directly accessing a private organization through: GET /api/v1/orgs/{org} However, that same token can still obtain private organization data through alternate code paths. The root cause is inconsistent enforcement of the public-only restriction. The middleware responsible for blocking non-public organization access depends on route context being populated with the target organization. That assumption does not hold for all affected routes. For GET /api/v1/user/orgs, the route does not apply checkTokenPublicOnly() at all. For GET /api/v1/users/{username}/orgs, the middleware is present, but it evaluates ctx.ContextUser, which represents the user named in the path, not the organiz
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
