+### View details of a DAST vulnerability
+
+Vulnerabilities detected by DAST occur in the live web application. Rectification of these types of
+vulnerabilities requires specific information. DAST provides the information required to
+investigate and rectify the underlying cause.
+
+To view details of DAST vulnerabilities:
+
+1. To see all vulnerabilities detected:
+
+   - In a project, go to the project's **{shield}** **Security & Compliance** page.
+   - Only in a merge request, go the merge request's **Security** tab.
+
+1. Click on the vulnerability's description. The following details are provided:

+#### Hide sensitive information in headers
+
+HTTP request and response headers may contain sensitive information, including cookies and
+authorization credentials. By default, content of specific headers are masked in DAST vulnerability
+reports. You can specify the list of all headers to be masked. For details, see
+[Hide sensitive information](dast/index.md#hide-sensitive-information).

 ### Dismissing a vulnerability
 
 To dismiss a vulnerability, you must set its status to Dismissed. Follow these steps to do so:
