CVE-2026-27602
March 25, 2026
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.
