CWE
KEV
| CWE ID | Description |
|---|---|
| CWE-285 | The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. |
| CWE-1220 | The product implements access controls via a policy or other feature with the intention to disable or restrict accesses (reads and/or writes) to assets in a system from untrusted agents. However, implemented access controls lack required granularity, which renders the control policy too broad because it allows accesses from unauthorized agents to the security-sensitive assets. |
