This flaw allows an unauthenticated user to call the registration endpoint and create a new account that is granted administrator privileges.

The EPSS score is reported as less than 1%, indicating a low but non\u2011zero likelihood of exploitation in the wild. The vulnerability is not listed in the CISA KEV catalog, but the combination of high severity, straightforward exploitation path, and the ability to generate privileged accounts makes this a high\u2011risk issue.
