High severityNVD Advisory· Published Mar 25, 2026· Updated Mar 26, 2026
Modoboa has an OS Command Injection
CVE-2026-27602
Description
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.
