Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 full match
prevents

Secure SDLC explicitly requires sanitized error handling and information disclosure controls.

PR.PS-01 mostly match
prevents

Hardened baselines and config management directly suppress verbose server error output.
