Quick fix

PYSEC-2026-2147 — dynaconf: upgrade to the fixed version with the command below.

pip install --upgrade 'dynaconf>=3.2.13'

Details

dynaconf is a configuration management tool for Python. Prior to version 3.2.13, Dynaconf is vulnerable to Server-Side Template Injection (SSTI) due to unsafe template evaluation in the @Jinja resolver. When the jinja2 package is installed, Dynaconf evaluates template expressions embedded in configuration values without a sandboxed environment. This issue has been patched in version 3.2.13.
