In RPyC 4.1.x through 4.1.1, a remote attacker can dynamically modify object attributes to construct a remote procedure call that executes code for an RPyC service with default configuration settings.
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
