CWE-607 Public Static Final Field References Mutable Object

A public or protected static final field references a mutable object, which allows the object to be changed by malicious code, or accidentally from another package.

• Integrity: Modify Application Data

• [Implementation] Protect mutable objects by making them private. Restrict access to the getter and setter as well.

• Automated Static Analysis: Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)
