CWE-758Reliance on Undefined, Unspecified, or Implementation-Defined Behavior
The product uses an API function, data structure, or other entity in a way that relies on properties that are not always guaranteed to hold for that entity.
This can lead to resultant weaknesses when the required properties change, such as when the product is ported to a different platform or if an interaction error (CWE-435) occurs.

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.
