NVD Description
Note: Versions mentioned in the description apply only to the upstream php-twig package and not the php-twig package as distributed by Ubuntu.
A sandbox information disclosure exists in Twig before 1.38.0 and 2.x before 2.7.0 because, under some circumstances, it is possible to call the __toString() method on an object even if not allowed by the security policy in place.
