Description
Missing authorization in the external management API in Amazon mcp-gateway-registry 1.0.9 through 1.24.7 might allow an authenticated remote user to assign the registry administrator scope to their own identity group and obtain administrative control of every registered gateway asset via a crafted group import request. To remediate this issue, users should upgrade to version 1.25.0.
