Quick fix

PYSEC-2026-2223 — modoboa: upgrade to the fixed version with the command below.

pip install --upgrade 'modoboa>=2.7.1'

Details

Modoboa is a mail hosting and management platform. Prior to version 2.7.1, `exec_cmd()` in `modoboa/lib/sysutils.py` always runs subprocess calls with `shell=True`. Since domain names flow directly into shell command strings without any sanitization, a Reseller or SuperAdmin can include shell metacharacters in a domain name to run arbitrary OS commands on the server. Version 2.7.1 patches the issue.
