Breaking encapsulation can lead to unreliable or insecure applications.
When encapsulation is broken, an object's internal state can be altered unpredictably, leading to bugs and vulnerabilities. In an e-commerce platform, if encapsulation is not properly maintained, a `Cart` class might expose its items list directly. This would allow external classes to modify the list without proper checks, potentially resulting in invalid cart states or data corruption.
