Detailed vulnerability description
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to improper access control in the FrameworkBundle form CSRF protection mechanism when processing forms without explicitly enabled CSRF protection. A remote attacker can cause the victim's browser to submit a crafted request to perform cross-site request forgery attacks.
The issue occurs when the application relies on the default configuration behavior and does not explicitly enable CSRF protection for forms.
