Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Jinja is an extensible templating engine. In versions on the 3.x branch prior to 3.1.5, a bug in the Jinja compiler allows an attacker that controls both the content and filename of a template to execute arbitrary Python code, regardless of if Jinja's sandbox is used. To exploit the vulnerability, an attacker needs to control both the filename and the contents 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 where the template author can also choose the template filename. This vulnerability is fixed in 3.1.5.

Recommended fix High confidence

Jinja 3.1.5

  1. 1. Identify the package manager used in your project (pip, poetry, pipenv, conda, etc.)
  2. 2. For pip users, run: pip install 'Jinja2>=3.1.5' or pip install Jinja2==3.1.5
  3. 3. For poetry users, run: poetry add Jinja2@^3.1.5
  4. 4. For pipenv users, run: pipenv install Jinja2==3.1.5
  5. 5. Verify the installation by checking the installed version: python -c 'import jinja2; print(jinja2.__version__)'
  6. 6. Ensure your application's automated tests pass after upgrading to confirm no regressions
Caveat Review the Jinja 3.1.5 release notes for any breaking changes from your current version; minor version bumps typically have minimal breaking changes
