Securing local network access: By default, the RPC interface can only be accessed by a client running on the same computer and only after the client provides a valid authentication credential (username and passphrase). For example basic usage (which can be easily modified for Bitcoin RPC see the Jansson example github_commits. Python-jsonrpc is the official json-RPC implementation for Python.
Jgarzik has forked it as Python-BitcoinRPC and optimized it for current versions. Secure string handling: The RPC interface does not guarantee any escaping of data beyond what's necessary to encode it as json, although it does usually provide serialized data using a hex representation of the bytes.
Thus, the mempool state only encompasses transactions that are considered mine-able by the node at the time of the RPC. Allowing arbitrary machines to access the json-RPC port (using the rpcallowip configuration option ) is dangerous and strongly discouraged - access should be strictly limited to trusted machines.

If you use RPC data in your programs or provide its data to other programs, you must ensure any problem strings are properly escaped. To prevent this from happening you might want to increase the number of maximum allowed file descriptors in your system and try to prevent opening too many connections to your json-RPC interface at the same time if this is under your control.

Additionally, the RPC interface has not been hardened to withstand arbitrary Internet traffic, so changing the above settings to expose it to the Internet (even using something like a Tor onion service) could expose you to unconsidered vulnerabilities.
