- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3715-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb January 23, 2024 https://wiki.debian.org/LTS

Package : jinja2 Version : 2.10-2+deb10u1 CVE ID : CVE-2024-22195 Debian Bug : 1060748

It was discovered that there was an injection attack in jinja2, a popular templating engine used in various Python applications.

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:
https://security-tracker.debian.org/tracker/jinja2

Solution

Upgrade the python-jinja2 packages.
