The femanager extension for TYPO3 allows Insecure Direct Object Reference resulting in unauthorized modification of userdata. This issue affects femanager version 6.4.1 and below, 7.0.0 to 7.5.2 and 8.0.0 to 8.3.0

Insecure Direct Object Reference (IDOR) in the femanager TYPO3 extension allows attackers to view frontend user data via a user parameter in the newAction of the newController.

An issue was discovered in the femanager extension before 5.5.3, 6.x before 6.3.4, and 7.x before 7.1.0 for TYPO3. Missing access checks in the InvitationController allow an unauthenticated user to delete all frontend users.

An issue was discovered in the femanager extension before 5.5.3, 6.x before 6.3.4, and 7.x before 7.1.0 for TYPO3. Missing access checks in the InvitationController allow an unauthenticated user to set the password of all frontend users.

The femanager extension before 5.5.2, 6.x before 6.3.3, and 7.x before 7.0.1 for TYPO3 allows creation of frontend users in restricted groups (if there is a usergroup field on the registration form). This occurs because the usergroup.inList protection mechanism is mishandled.

The femanager extension before 5.5.1 and 6.x before 6.3.1 for TYPO3 allows XSS via a crafted SVG document.

The femanager extension before 1.0.9 for TYPO3 allows remote frontend users to modify or delete the records of other frontend users via unspecified vectors.
