CWE-460Improper Cleanup on Thrown Exception

Abstraction: Base · CVEs in our corpus: 26

The product does not clean up its state or incorrectly cleans up its state when an exception is thrown, leading to unexpected state or control flow.

Often, when functions or loops become complicated, some level of resource cleanup is needed throughout execution. Exceptions can disturb the flow of the code and prevent the necessary cleanup from happening.

NIST 800-53 r5 controls PROPOSED for this weakness (0)AI-assisted

These are model PROPOSALS, not graded mappings. They come from controls_to_cwe_proposals, which carries no grade field at all; across the CWE pages 1,540 of 1,722 such associations (89%) have never been graded by anything. The heading said “address” until 2026-09-29, which asserted a relationship the data does not carry. Graded cross-walks are on the framework map, not here.
