CVE-2026-30452

A.5.15 directly mandates determining requirements, defining/implementing topic-specific access control policy+rules (with explicit references to 8.3, 5.16, 5.18), and enforcing authorized access while preventing unauthorized access, which squarely stops exploitation of most CWE-284 instances; the bounded remainder is the physical slice (explicitly delegated to 7.2-7.4) plus any second-order defects like path traversal that are not authorization decisions.

A.5.16's identity lifecycle (unique binding, timely disable/remove, no duplicates, oversight of shared/non-human) directly stops most improper access by ensuring the actor in an access decision is correctly identified and authorized; the bounded remainder is non-identity mechanisms in CWE-284 such as path traversal or CSRF that do not turn on actor identity at all.

A.5.18 directly governs the provisioning, review, adjustment and timely revocation of both physical and logical access rights per business rules, segregation of duties and risk-evaluated changes/terminations; this stops most unauthorized-actor exploitation paths named by CWE-284, with a bounded remainder (e.g. path-traversal or CSRF cases that are not authorization decisions at all)

A.6.7's policy, rules, mechanisms, authentication requirements, remote access controls, network restrictions, and device measures (e.g. screen locks, firewalls, malware protection) directly stop unauthorized actors from exploiting improper access control in remote settings; remainder is non-remote or physical-only slices of CWE-284 (as in AC-3's own mostly precedent).

A.8.1 mandates access controls, storage encryption, software restrictions, malware protection, remote lock/wipe, physical/logical device protections, and policy-driven enforcement that stop unauthorized actors from exploiting improper access control on endpoints; remainder is non-endpoint or non-device slices of CWE-284 (e.g. server-side authorization logic).

A.8.2 directly controls allocation, review, expiry, temporary use, separate identities and heightened authentication for privileged rights per the access policy, which stops most improper-access-control exploitation paths for privileged resources; the bounded remainder is non-privileged improper access control (e.g. ordinary user rights, path traversal, CSRF).
