Symfony Open Redirect

  • Disclosed: 14.05.2022
  • Updated: 11.10.2026 10:22

An open redirect was discovered in Symfony 2.7.x before 2.7.50, 2.8.x before 2.8.49, 3.x before 3.4.20, 4.0.x before 4.0.15, 4.1.x before 4.1.9 and 4.2.x before 4.2.1. By using backslashes in the _failure_path input field of login forms, an attacker can work around the redirection target restrictions and effectively redirect the user to any domain after login.
