$doc.body.appendChild(scriptFrame);
and probably due to that line:
scriptFrame.src = $intern_10;
because of:
$intern_10 = 'javascript:""'
This was actually fixed in 2.8.2: https://github.com/gwtproject/gwt/commit/f5df41df4016cd2ce4e6a15a637dbe2ddc4f3fab, so you're probably using an older version.
One workaround, as described in the comments in that file is to extend CrossSiteIframeLinker and override getJsInstallLocation() to return your own script where you'd have applied the fix.
…but then things will break in installCode and __installRunAsyncCode, coming from https://github.com/gwtproject/gwt/blob/2.8.2/dev/core/src/com/google/gwt/core/ext/linker/impl/installScriptDirect.js and https://github.com/gwtproject/gwt/blob/2.8.2/dev/core/src/com/google/gwt/core/ext/linker/impl/runAsync.js respectively.
You'll want to replace those with modified versions (read CrossSiteIframeLinker to see how to override them) that will add the nonce to the dynamically created script (though as they're injected into the iframe that's been dynamicallly created in setupInstallLocation, I'm not sure how/which CSP applies there)

Hi TeamHope you are doing welli am using GWT version 2.8.2i am trying to apply content secure policy in GWT using script-src 'self' and object-src 'self' without unsafe-inline and unsafe-eval but i am getting belowsetupInstallLocation @ AllDec.nocache.js?timeStamp=1709618887261:71
AllDec.nocache.js?timeStamp=1709618887261:71 Refused to run the JavaScript URL because it violates the following Content Security Policy directive: "script-src 'self' 'nonce-alldec202403040001' 'nonce-alldec202403040002' 'nonce-trwFrame-202403040001' 'nonce-footer-202403040001' 'nonce-menu202403040001' 'nonce-Header2022092604' 'nonce-Header2022092603' 'nonce-Header2022092602' 'nonce-Header2022092601' 'nonce-header-momentjs-20221027' 'nonce-header-inline-2022102701' 'nonce-header-inline-2022102702'". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution. Note that hashes do not apply to event handlers, style attributes and javascript: navigations unless the 'unsafe-hashes' keyword is present.my code logic with different approaches and none of them work for me

Need your valuable inputs to achieve content secure policy in GWT using script-src 'self' and object-src 'self' without unsafe-inline and unsafe-evali suspect the inline java script code is not allowing to apply script-src 'self' and object-src 'self' without unsafe-inline and unsafe-evalhere is my AllDec.nocache.jsfunction AllDec(){
