Name of the Vulnerable Software and Affected Versions
Pallets Jinja versions prior to 2.10.1
Description
The issue allows a sandbox escape through the
str.format map method. This method could be used to bypass the sandbox, which is designed to restrict the evaluation of untrusted, user-provided templates. The problem arises due to the way string formatting works in Python.Recommendations
For versions prior to 2.10.1, update to version 2.10.1 or later to resolve the issue.
As a temporary workaround, consider overriding the
is safe attribute method on the sandbox and explicitly disallow the format map method on string objects.Correção
