Jupyter Server versions from 2.0.0 up to but not including 2.6.0 have a missing authorization check vulnerability when GatewayClient.url is enabled. This flaw allows an authenticated but restricted user to bypass authorization controls and execute code on the kernel, potentially exposing sensitive data and allowing modification or disruption of the kernel environment. The issue is fixed in version 2.6.0 for default gateway configurations. However, in 2.6.0 and later, if the deprecated jupyter_server.gateway.handlers module is manually registered, the authorization bypass remains possible.
