Cross-site request forgery in XWiki Platform before 12.10.5 and 13.0 through 13.1 allows remote attackers to disclose wiki usernames. The ForgotUsername page accepts an email address without validating a CSRF token and returns usernames associated with a matching account. No authentication is required; the response reveals whether an email is registered and which usernames are linked to it.
