If there is a claim dialect configured with an XSS payload in the dialect URI, if a user picks up the malicious dialect URI and adds it as the service provider claim dialect while configuring the service provider, that payload gets executed. The attacker also needs to have privileges to log in to the management console, add and configure claim dialects.
