Mitigating Controls

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.

AC-24 Access Control Decisions
addresses: CWE-639

Per-request decision making makes it harder to bypass authorization using user-controlled keys without proper validation in the decision process.

AC-3 Access Enforcement
addresses: CWE-639

Consistent enforcement of approved authorizations makes bypassing via user-controlled keys ineffective.

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.AA-05 full match
prevents

Enforcing authorization policy and least privilege directly blocks user-controlled key tampering that bypasses access checks.

PR.IR-01 mostly match
prevents

Logical access controls prevent unauthorized data access that results from missing authorization checks on object references.

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
detects

Security testing can detect missing authorization checks but does not prevent the weakness in production.

A.8.3 Information access restriction mostly match
prevents

Information access restriction explicitly enforces that users may only retrieve data they are authorized to see, directly addressing user-controlled key bypass.

A.5.15 Access control partial match
prevents

Access control policy directly requires enforcement of authorization rules that prevent unauthorized access via manipulated keys.

A.5.18 Access rights partial match
prevents

Managing access rights includes ensuring users can only access their own records and not bypass authorization by altering identifiers.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights control restricts what data each user may access, mitigating direct object reference attacks.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes authorization design but does not itself implement runtime access checks.
