NVD Description

Note: Versions mentioned in the description apply only to the upstream symfony package and not the symfony package as distributed by Ubuntu.

In Symfony before 2.7.51, 2.8.x before 2.8.50, 3.x before 3.4.26, 4.x before 4.1.12, and 4.2.x before 4.2.7, validation messages are not escaped, which can lead to XSS when user input is included. This is related to symfony/framework-bundle.
