Description
# Description When using the filesystem loader to load 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). # Resolution We fixed validation for such template names. Even if the 1.x branch is not maintained anymore, a new version has been released. # Credits We would like to thank Dariusz Tytko for reporting the issue and Fabien Potencier for fixing the issue.
