Description

An issue was discovered in Symfony 2.7.x before 2.7.38, 2.8.x before 2.8.31, 3.2.x before 3.2.14, and 3.3.x before 3.3.13. DefaultAuthenticationSuccessHandler or DefaultAuthenticationFailureHandler takes the content of the _target_path parameter and generates a redirect response, but no check is performed on the path, which could be an absolute URL to an external domain. This Open redirect vulnerability can be exploited for example to mount effective phishing attacks.
