This entry has been deprecated and consolidated into CWE-199: Information Management Errors. Please refer to that entry for current information.
This deprecated category previously grouped various weaknesses related to how software handles, stores, or transmits information incorrectly. These issues often stem from flawed logic or inadequate validation when managing data structures, system state, or user-provided input, which could lead to unexpected behavior or security vulnerabilities. For up-to-date guidance, developers should consult CWE-199, which provides a modern framework for understanding how mismanagement of information—such as improper error handling, incorrect calculations, or flawed state tracking—can create exploitable conditions in an application. Focusing on robust data validation, consistent state management, and clear error handling remains critical for preventing this class of weaknesses.
