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.
Requiring a decision for every access request prevents missing authorization checks that would otherwise allow unauthorized access.
Always invoking the reference monitor prevents missing authorization checks for protected resources.
Requiring enforcement of authorizations ensures checks are performed rather than omitted for resources.
Decoy endpoints catch forced browsing and direct requests, deflecting attackers from legitimate resources while enabling analysis.
Prevents missing authorization checks for input operations by restricting the capability itself.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
