CWE-459 (清理环节不完整) — Vulnerability Class 51

CWE-459 represents a resource management weakness where software fails to properly release temporary or supporting resources after their intended use. This oversight typically leads to resource exhaustion, such as memory leaks, file descriptor saturation, or disk space depletion, which can degrade system performance or cause denial-of-service conditions. Attackers often exploit this by repeatedly triggering operations that allocate resources without releasing them, effectively starving the system of necessary assets. To mitigate this risk, developers must implement rigorous cleanup protocols, ensuring that all allocated resources are explicitly freed or closed within finally blocks or using automatic resource management constructs like context managers. Adhering to strict lifecycle management practices and conducting thorough code reviews helps prevent these leaks, maintaining system stability and security integrity.
