.
* Non-maintainer upload by the LTS security team.
* Fix CVE-2024-56201:
In versions on the 3.x branch prior to 3.1.5, a bug in the Jinja compiler
allows an attacker that controls both the content and filename of a template
to execute arbitrary Python code, regardless of if Jinja's sandbox is used.
To exploit the vulnerability, an attacker needs to control both the filename
and the contents of a template. Whether that is the case depends on the type
of application using Jinja. This vulnerability impacts users of applications
which execute untrusted templates where the template author can also choose
the template filename.
* Fix CVE-2024-56326:
Prior to 3.1.5, An oversight in how the Jinja sandboxed environment detects
calls to str.format allows an attacker that controls the content of a
template to execute arbitrary Python code. To exploit the vulnerability, an
attacker needs to control the content of a template. Whether that is the
case depends on the type of application using Jinja. This vulnerability
impacts users of applications which execute untrusted templates. Jinja's
sandbox does catch calls to str.format and ensures they don't escape the
sandbox. However, it's possible to store a reference to a malicious string's
format method, then pass that to a filter that calls it. No such filters are
built-in to Jinja, but could be present through custom filters in an
application. After the fix, such indirect calls are also handled by the
sandbox.
