Vulnerability details
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.

This Open redirect vulnerability can be exploited for example to mount effective phishing attacks.
