Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Jinja2 versions 3.0.0 up to but not including 3.1.5 are vulnerable. An attacker who controls both the content and the filename of a template can execute arbitrary Python code, even when Jinja's sandbox is used. Exploitation depends on the application, and the risk applies to applications that run untrusted templates where the template author can also pick the filename. Upgrade to jinja2 3.1.5.
