CVE-2019-10069

In Godot through 3.1, remote code execution is possible due to the deserialization policy not being applied correctly.

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Name	Vendor	Start Version	End Version
Godot	Godotengine	*	2.1 (excluding)
Godot	Godotengine	2.1.1 (including)	3.1 (including)
Godot	Ubuntu	disco	*
Godot	Ubuntu	eoan	*
Godot	Ubuntu	focal	*

Make fields transient to protect them from deserialization.
An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
