Description
The extension's invitation controller fails to stop processing after redirecting on invalid input (missing hash, non-existent, disabled, or deleted users), allowing an unauthenticated attacker to set a new password for and re-enable an arbitrary existing frontend user account. This vulnerability is only present in the 8.x versions of the extension.
