CVE-2024-22195

Jinja is an extensible templating engine. Special placeholders in the template allow writing code similar to Python syntax. It is possible to inject arbitrary HTML attributes into the rendered HTML template, potentially leading to Cross-Site Scripting (XSS). The Jinja xmlattr filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.

The Jinja xmlattr filter can be abused to inject arbitrary HTML attribute keys and values, bypassing the auto escaping mechanism and potentially leading to XSS. It may also be possible to bypass attribute validation checks if they are blacklist-based.

The xmlattr filter in affected versions of Jinja accepts keys containing spaces. XML/HTML attributes cannot contain spaces, as each would then be interpreted as a separate attribute. If an application accepts keys (as opposed to only values) as user input, and renders these in pages that other users see as well, an attacker could use this to inject other attributes and perform XSS. Note that accepting keys as user input is not common or a particularly intended use case of the xmlattr filter, and an application doing so should already be verifying what keys are provided regardless of this fix.

Jinja2 is one of the most used template engines for Python. It is inspired by Django's templating system but extends it with an expressive language that gives template authors a more powerful set of tools. On top of that it adds sandboxed execution and optional automatic escaping for applications where security is important.

Security Fix(es):

TuxCare rebuilt jinja2 to address 4 CVEs. Fixed in 2.11.3.post1+tuxcare.

TuxCare rebuilt jinja2 to address 3 CVEs. Fixed in 3.0.3.post1+tuxcare.

It was discovered that Jinja2 incorrectly handled certain HTML attributes that were accepted by the xmlattr filter. An attacker could use this issue to inject arbitrary HTML attribute keys and values to potentially execute a cross-site scripting (XSS) attack.

These are all security issues fixed in the python310-Jinja2-3.1.3-1.1 package on the GA media of openSUSE Tumbleweed.

These are all security issues fixed in the python313-Jinja2-3.1.6-2.4 package on the GA media of openSUSE Tumbleweed.
