How to fix?

Upgrade symfony/security-bundle to version 5.3.12 or higher.

Overview

symfony/security-bundle is a security bundle for Symfony.

Affected versions of this package are vulnerable to Improper Authentication since the remember me cookie is not invalidated anymore after the user changes its password.

Attackers can maintain their access to the account even if the password is changed as long as they have had the chance to login once and get a valid remember me cookie.
