The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream twig package and not the twig package as distributed by Ubuntu.
Twig before 2.4.4 allows Server-Side Template Injection (SSTI) via the search search_key parameter. NOTE: the vendor points out that Twig itself is not a web application and states that it is the responsibility of web applications using Twig to properly wrap input to it
