## Class Script

- java.lang.Object
- - org.apache.struts2.components.Component
  - - org.apache.struts2.components.UIBean
    - - org.apache.struts2.components.ClosingUIBean
      - - org.apache.struts2.components.Script

-     public class Script
      extends ClosingUIBean

  Add nonce propagation feature to implement CSP in script tags

  The script tag allows the user to execute JavaScript. It also allows external resources to execute scripts which can be malicious. The s:script tag includes a nonce attribute that is being randomly generated with each request and only allows scripts with the valid nonce value to be executed.

  Examples

       <s:script ... />
