Remediation Suggestions
- Remove
--open-idfrom the public CLI and do not permit ordinary callers to select an account identity. - Obtain identity only from an authenticated, integrity-protected upstream context. Use a signed assertion with issuer, audience, expiration, and nonce validation.
- Require the server to verify ownership before issuing tokens. An identifier alone must never be sufficient for login or token creation.
- Disable silent registration/login for arbitrary supplied identifiers. Registration and authentication should be separate, explicitly authorized operations.
- Bind report queries to the subject encoded in the authenticated server-issued token rather than accepting a client-selected user identifier.
- If an internal identity override is operationally necessary, restrict it to an administrator-only interface and require explicit authorization checks, audit logging, and a narrowly scoped impersonation grant.
- Avoid storing tokens obtained through unverified identity assertions. Invalidate any tokens previously issued through this flow and review associated access logs for cross-account activity.
- Add negative authorization tests proving that one user cannot obtain credentials or report records by submitting another user’s Open ID.
- Remove
