When you run vulnerability scans, images that are subject to Common Vulnerabilities and Exposures (CVE) are identified. According to the severity of the CVE and your security settings, these images might not be permitted to run. You can create whitelists of CVEs to ignore during vulnerability scanning.
Harbor administrators can set a system-wide CVE whitelist. For information about site-wide CVE whitelists, see [Configure System-Wide CVE Whitelists](../administration/vulnerability_scanning/configure_system_whitelist.md). By default, the system whitelist is applied to all projects. You can configure different CVE whitelists for individual projects, that override the system whitelist.
After you have created a project whitelist, you can remove CVE IDs from the list by clicking the delete button next to it in the list. You can click **Add** at any time to add more CVE IDs to this project whitelist.
If CVEs are added to the system whitelist after you have created a project whitelist, click **Copy From System** to add the new entries from the system whitelist to the project whitelist.
**NOTE**: If CVEs are deleted from the system whitelist after you have created a project whitelist, and if you added the system whitelist to the project whitelist, you must manually remove the deleted CVEs from the project whitelist. If you click **Copy From System** after CVEs have been deleted from the system whitelist, the deleted CVEs are not automatically removed from the project whitelist.
