Hi,

Jinja 2.7.2 was just released and includes a fix for a security problem with the file system bytecode cache. The default location for the filesystem on Linux systems used to be not user specific and as such allowed attackers on the same system to place files there that Jinja2 would then import.

The solution for this has been the introduction of a directory for that particular user, however the correct solution is to not place the bytecode cache in the global temporary folder at all and use an explicit path instead.

For 2.8 I will look at better options to solve this issue.

Regards,
Armin
