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.DS-10 partial match

Explicitly calls for removing confidential data from processes, logs, and memory dumps that debug code commonly exposes.

PR.PS-01 partial match
blocks

Hardened configuration baselines and deployment checks can ensure debug features and associated data are disabled in production.

PR.PS-06 partial match

Secure SDLC practices directly prevent developers from embedding sensitive information inside debugging statements or code paths.

Secure SDLC mandates removal of debug code and sensitive data before release.

Secure coding standards explicitly prohibit embedding secrets or debug statements.

A.8.31 Separation of development, test and production environments partial match
blocks

A.8.31 separates environments and restricts what reaches production; it does not stop sensitive information from being inserted into debugging code in the first place, so the weakness can still be present and exploitable if debugging code slips into production.
