Remediation

Vendor Solution

IBM strongly recommends addressing the vulnerability now. Product(s)Version(s) number and/or range Remediation/Fix/InstructionsIBM ContextForge MCP Gatewayv1.0.0 - v1.0.9Upgrade to v1.0.10. See release notes. Additionally, ensure platform_admin_password, default_user_password, and basic_auth_password are set to strong, non-default values before enabling api_allow_basic_auth or mcpgateway_ui_enabled. Note: <Component A / B names> are bundled with <Product profile name> to provide <feature / function description>


Vendor Workaround

On a default deployment, api_allow_basic_auth and mcpgateway_ui_enabled are both set to False, which prevents the default credentials from being exposed through an active authentication path. Operators who have not enabled either of these features are not immediately at risk. If upgrading is not immediately possible, ensure both features remain disabled until the password fields are set to strong, operator-defined values.
