The TYPO3 Extension femanager prior to versions 5.5.2, 6.3.3, and 7.0.1 is vulnerable to broken access control. The usergroup.inList validation can be bypassed resulting in new frontend users created by the extension may be members of groups that are restricted. The vulnerability is only exploitable if the field usergroup is available in the registration form. Versions 5.5.2, 6.3.3, and 7.0.1 contain patches.
