CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-862Missing Authorization11,800+Requiring a decision for every access request prevents missing authorization checks that would otherwise allow unauthorized access.
CWE-284Improper Access Control8,100+Ensuring access control decisions are made and applied to every request before enforcement directly prevents improper access control by requiring policy-based checks.
CWE-863Incorrect Authorization4,800+Applying decisions to each request prior to enforcement mitigates incorrect authorization by enforcing consistent policy evaluation.
CWE-639Authorization Bypass Through User-Controlled Key3,300+Per-request decision making makes it harder to bypass authorization using user-controlled keys without proper validation in the decision process.
CWE-285Improper Authorization1,700+The control mandates authorization decisions for each access request, reducing the ability to exploit improper authorization weaknesses.
CWE-425Direct Request ('Forced Browsing')200+Forcing a decision on every access request, including direct ones, reduces the exploitability of forced browsing by ensuring no unchecked access paths.
