Technical details

A reflected XSS vulnerability exists in the documentName parameter of Fusion protocol URLs. When a user invokes a malicious protocol URL, unsanitized HTML payloads are rendered in the application context, allowing script execution with the privileges of the running process. An attacker can craft a link to trigger arbitrary JavaScript or read sensitive local files without requiring authentication.
