Xen Orchestra before 6.9.0 contains an authorization bypass vulnerability in the xo-server user.set API method that allows low-privileged authenticated users to modify other users' preferences by supplying an arbitrary target user id. Attackers can delete the preferences.otp TOTP secret to disable two-factor authentication, corrupt it to block logins, or overwrite stored xsCredentials and sshKeys.
