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.

SC-44 Detonation Chambers
addresses: CWE-470

Externally controlled class or code selection can be resolved and invoked inside the chamber, surfacing unsafe reflection without system impact.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover unsafe reflection during code review or scanning.

PR.PS-05 partial match
prevents

Preventing execution of unauthorized code can block exploitation of unsafe reflection at runtime.

PR.PS-06 partial match
prevents

Secure SDLC practices directly avoid introducing externally controlled class selection via reflection.

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.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates input validation and design reviews that reduce unsafe reflection risks.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly prohibit or constrain reflection based on untrusted input.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles discourage dynamic class loading from external data sources.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid unsafe reflection and require whitelisting or static alternatives.

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

Security testing can detect and block unsafe reflection patterns before release.
