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.

Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue when the filesystem loader loads templates for which the name is a user input. It is possible to use the source or include statement to read arbitrary files from outside the templates' directory when using a namespace like @somewhere/../some.file. In such a case, validation is bypassed. Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such template names. There are no known workarounds aside from upgrading.
