This CWE entry has been retired. It was originally created to describe a specific type of bug where code incorrectly compares two objects that should be considered the same, but the description was too vague and overlapped with other weaknesses. It has been consolidated into CWE-1023.
This entry was deprecated because it was difficult for developers to apply. The original concept—faulty logic when checking if two objects represent the same real-world entity—was too tightly coupled to specific application domains and wasn't described in a clear, general way. This made it hard to distinguish from more fundamental comparison flaws, leading to confusion rather than clarity. For current guidance, developers should refer to CWE-1023 (Incomparable Values). Focus on ensuring your comparison operations (like using `.equals()` in Java or `==` in JavaScript) correctly match the semantics you intend for your data objects. Always verify that the logic for determining object equality aligns with the business rules of your application, not just superficial attributes.
