CVE-2025-27516

一、漏洞信息
 漏洞编号：[CVE-2025-27516](https://nvd.nist.gov/vuln/detail/CVE-2025-27516)
 漏洞归属组件：[python-jinja2](https://gitee.com/src-openeuler/python-jinja2)
 漏洞归属的版本：2.11.2,2.11.3,3.0.3,3.1.2,3.1.3,3.1.6
 CVSS V3.0分值：
  BaseScore：8.8 High
  Vector：CVSS：3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
 漏洞简述：
  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.
