Summary

It was possible to inject arbitrary HTML attributes into rendered
HTML via the "xmlattr" filter, potentially leading to a Cross-Site
Scripting (XSS) attack. It may also have been possible to bypass
attribute validation checks if they were blacklist-based.

For Debian 10 buster, this problem has been fixed in version
2.10-2+deb10u1.

We recommend that you upgrade your jinja2 packages.

For the detailed security status of jinja2 please refer to
its security tracker page at:
