CVE-2025-27516
An oversight in how the Jinja sandboxed environment interacts with the
|attrfilter 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.formatand ensures they don't escape the sandbox. However, it's possible to use the|attrfilter to get a reference to a string's plain format method, bypassing the sandbox. After the fix, the|attrfilter no longer bypasses the environment's attribute lookup.Release Notes
