In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, a vulnerability would allow an attacker to authenticate as a privileged user on sites with user registration and remember me login functionality enabled. This is related to symfony/security.
Weakness
When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
