Weaknesses this control addresses (4)AI-assisted
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-862 | Missing Authorization | 11,800+ | Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review. |
CWE-284 | Improper Access Control | 8,100+ | Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions. |
CWE-306 | Missing Authentication for Critical Function | 3,900+ | Requiring identification and rationale for actions allowed without authentication ensures critical functions are not left unprotected by forcing review of authentication requirements. |
CWE-285 | Improper Authorization | 1,700+ | The control's documentation requirement reduces improper authorization by ensuring only mission-justified actions bypass authentication. |
