Summary
[none]
Details

In a scenario of a multilingual website with different domain names per language, this module enables you to be automatically connected across the language domains if you are logged on the main language domain.

The module doesn't sufficiently validate a short-lived token, allowing an attacker to bypass access control and authenticate as a victim user.

This vulnerability is mitigated by the fact that an attacker must appear to originate from the same client IP as the victim.
