Cross-site request forgery (CSRF) vulnerability in the Subuser module before 6.x-1.8 for Drupal allows remote attackers to hijack the authentication of arbitrary users for requests that switch the user to a subuser via unspecified vectors.

The Subuser module before 6.x-1.8 for Drupal does not properly check "switch subuser" permissions, which allows remote authenticated parent users to change their role by switching to a subuser they created.
