Improper Certificate Validation in apache airflow mongo hook

Quick fix

PYSEC-2026-278 — apache-airflow-providers-mongo: upgrade to the fixed version with the command below.

pip install --upgrade 'apache-airflow-providers-mongo>=4.0.0'

Details

When ssl was enabled for Mongo Hook, default settings included "allow_insecure" which caused that certificates were not validated. This was unexpected and undocumented. Users are recommended to upgrade to version 4.0.0, which fixes this issue.
