Description
Dolibarr before 24.0.0 contains a reflected cross-site scripting vulnerability in the extra fields administration template where the type request parameter is echoed without JavaScript-context encoding into an inline script block and no Content-Security-Policy header is emitted. An unauthenticated attacker can cause an authenticated administrator to open a crafted URL to execute arbitrary JavaScript in that session and create a persistent administrator account.
