# Django 1.4.7 release notes

Django 1.4.7 fixes one security issue present in previous Django releases in the 1.4 series.

## Directory traversal vulnerability in `ssi` template tag

In previous versions of Django it was possible to bypass the `ALLOWED_INCLUDE_ROOTS` setting used for security with the `ssi` template tag by specifying a relative path that starts with one of the allowed roots. For example, if `ALLOWED_INCLUDE_ROOTS = ("/var/www",)` the following would be possible:

    {% ssi "/var/www/../../etc/passwd" %}

In practice this is not a very common problem, as it would require the template author to put the `ssi` file in a user-controlled variable, but it’s possible in principle.
