Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-6 Security and Privacy Function Verification
addresses: CWE-684

Periodic checks confirm that specified security and privacy functions are actually provided and operating.

Mitigating Controls (NIST CSF 2.0) AI

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 mostly match
prevents

Secure SDLC practices directly enforce spec-compliant functionality and testing, while eliminating this weakness fulfills only part of the control's broader monitoring intent.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development and acceptance validates that implemented functionality conforms to specifications before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle includes requirements and verification activities that directly reduce the risk of delivering functionality that deviates from published specifications.

A.8.26 Application security requirements partial match
prevents

Explicit application security requirements and acceptance criteria help ensure the delivered software matches its intended specifications.

A.8.32 Change management partial match
prevents

Change management processes reduce the chance of unintended functional deviations during updates, though they do not directly address initial specification conformance.

Hardening callouts derived
