EulerOS Virtualization 2.10.0 : python-jinja2 (EulerOS-SA-2026-1193)

medium Nessus Plugin ID 297321

Synopsis

The remote EulerOS Virtualization host is missing a security update.

Description

According to the versions of the python-jinja2 package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

 Jinja is an extensible templating engine. Prior to 3.1.6, an oversight in how the Jinja sandboxed environment interacts with the |attr filter allows an attacker that controls the content of a template to execute arbitrary Python code. To exploit the vulnerability, an attacker needs to control the content of a template. Whether that is the case depends on the type of application using Jinja. This vulnerability impacts users of applications which execute untrusted templates. Jinja's sandbox does catch calls to str.format and ensures they don't escape the sandbox. However, it's possible to use the |attr filter to get a reference to a string's plain format method, bypassing the sandbox. After the fix, the |attr filter no longer bypasses the environment's attribute lookup. This vulnerability is fixed in 3.1.6.(CVE-2025-27516)

Tenable has extracted the preceding description block directly from the EulerOS Virtualization python-jinja2 security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-jinja2 packages.
