"category": "general",
"text": "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\u0027s sandbox does catch calls to str.format and ensures they don\u0027t escape the sandbox. However, it\u0027s possible to use the |attr filter to get a reference to a string\u0027s plain format method, bypassing the sandbox. After the fix, the |attr filter no longer bypasses the environment\u0027s attribute lookup. This vulnerability is fixed in 3.1.6.",
