Description filip ambroz 2022-09-29 07:30:05 UTC
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).

(fixed in version 1.44.7)

Please note:
1.x branch is not maintained anymore, a new versions have been released
