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CWE-200 | Exposure of Sensitive Information to an Unauthorized Actor | 11,000+ | Regular deletion of inaccurate or outdated PII directly reduces the volume of sensitive information retained that could be exposed. |
CWE-359 | Exposure of Private Personal Information to an Unauthorized Actor | 200+ | Targeted operations on PII accuracy, timeliness, and deletion reduce the risk of private personal information remaining available for unauthorized exposure. |
CWE-212 | Improper Removal of Sensitive Information Before Storage or Transfer | 100+ | The explicit requirement to delete inaccurate/outdated PII implements proper removal of sensitive information before further storage or transfer. |
CWE-226 | Sensitive Information in Resource Not Removed Before Reuse | 36 | Periodic quality checks and deletion ensure sensitive PII is removed from resources prior to reuse or retention beyond its valid lifetime. |
