You can ignore vulnerabilities so they do not appear as actionable issues in the detections list.
To ignore the finding, and from the Quick Actions menu, click Ignore.
In the Ignore QID(s) dialog box, from the Reason list, select the reason for ignoring the selected finding, whether the finding is an acceptable risk, false positive, or not applicable.
Once you click Ignore, the QID is ignored, and the finding is grayed out in the Knowledgebase tab.
By default, the ignored finding does not appear in future reports on the same web application or scan, until it is reactivated.
