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.
