Official description
In version 3.23.0 of aimhubio/aim, certain methods that request data from external servers do not have set timeouts, causing the server to wait indefinitely for a response. This can lead to a denial of service, as the tracking server does not respond to other requests while waiting. The issue arises in the client used by the `aim` tracking server to communicate with external resources, specifically in the `_run_read_instructions` method and similar calls without timeouts.

The underlying weakness: Synchronous Access of Remote Resource without Timeout
The code has a synchronous call to a remote resource, but there is no timeout for the call, or the timeout is set to infinite.
