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 8 jessie, these problems have been fixed in version 2.7.3-1+deb8u1.
For Debian 9 stretch, these problems have been fixed in version 2.8-1+deb9u1.
We recommend that you upgrade your jinja2 packages.
