Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires input validation to neutralize untrusted data before dynamic evaluation, exactly addressing the CWE-95 eval injection fixed by improved validation.

AC-3 Access Enforcement good match
prevent

Enforces that apps cannot access sensitive user data without explicit authorization, blocking the unauthorized data exposure resulting from the injection.

AC-6 Least Privilege partial match
prevent

Limits app privileges so that even a successful injection cannot reach sensitive user data beyond the minimal permissions granted.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input neutralization and avoidance of unsafe dynamic evaluation.

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

Security testing in development can detect eval injection vulnerabilities before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and safe coding practices that directly prevent eval injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements include rules against dynamic code execution of untrusted input.

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

Secure architecture principles discourage unsafe dynamic evaluation constructs.

A.8.28 Secure coding partial match
prevents

Secure coding explicitly requires neutralization of input before dynamic evaluation, directly mitigating eval injection.

A.8.31 Separation of development, test and production environments none match
none

Separation of environments limits the blast radius if eval injection occurs in non-production.
