Weaknesses this control addresses (3)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-284 | Improper Access Control | 6,900+ | Requiring explicit identification of the authorizing authority and processing purposes in a publicly available notice increases accountability and makes covert improper access control decisions harder to sustain. |
CWE-285 | Improper Authorization | 1,500+ | Mandating disclosure of the specific authority that authorizes PII processing and the exact purposes directly surfaces authorization decisions, reducing the viability of hidden or improper authorization. |
CWE-359 | Exposure of Private Personal Information to an Unauthorized Actor | 200+ | Clear, plain-language notice of PII processing authority, purposes, and scope creates transparency that makes unauthorized exposure of private personal information more likely to be detected and challenged by individuals. |
