[jira] [Created] (MYFACES-4479) The jsf.js script does not read the nonce correctly in modern browsers.

Vitaly Sidorov created MYFACES-4479:
---------------------------------------

             Summary: The jsf.js script does not read the nonce correctly in modern browsers.
                 Key: MYFACES-4479
                 URL: https://issues.apache.org/jira/browse/MYFACES-4479
             Project: MyFaces Core
          Issue Type: Bug
          Components: General
    Affects Versions: 2.3-next-M7
         Environment: Myfaces 2.3-next-M7
Chrome: 106.0.5249.103
            Reporter: Vitaly Sidorov


In Chrome it is no longer possible to get a nonce with getAttribute("nonce").

You can only use HTMLElement.nonce (see: [https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/nonce)]

Steps to reproduce:
- set header Content-Security-Policy: script-src 'self' 'nonce-test123'
- set <h:outputScript pt:nonce="test123" library="javax.faces" name="jsf.js" target="head"/>
- set parameters org.apache.myfaces.USE_MULTIPLE_JS_FILES_FOR_JSF_UNCOMPRESSED_JS=false and javax.faces.PROJECT_STAGE=Developement
- open page in browser and get multiple errors in console: 

{{jsf.js.jsf?ln=javax.faces&stage=Development:93 Refused to execute inline script because it violates the following Content Security Policy directive: "script-src 'self' 'nonce=test123'". Either the 'unsafe-inline' keyword, a hash ('sha256-Xu6aRWi9bDVg9FaanKbn/uUSQUCsJ5g+bPB5SUYUIfk='), or a nonce ('nonce-...') is required to enable inline execution.}}


The reason:
The error falls on .appendChild(element) in code

{{var htmlScriptElement = document.head.appendChild(element);}}
{{document.head.removeChild(htmlScriptElement);}}
