A POST based reflected Cross Site Scripting vulnerability on has been identified in Keycloak. When a malicious request is sent to the client registration endpoint, the error message is not properly escaped, allowing an attacker to execute malicious scripts into the user's browser.
Keycloak would like to thank Quentin TEXIER (Pentester at Opencyber) for reporting this issue.
