CVE-2026-25134

Name of the Vulnerable Software and Affected Versions Group-Office versions prior to 6.8.150 Group-Office versions prior to 25.0.82 Group-Office versions prior to 26.0.5

Description Group-Office is a customer relationship management and groupware tool. The MaintenanceController includes a zipLanguage action that uses a lang parameter directly in a system zip command via the exec() function. This can be exploited by uploading a specially crafted zip file, leading to remote code execution. The lang parameter is not properly filtered, allowing for command injection.

Recommendations Update Group-Office to version 6.8.150 or later. Update Group-Office to version 25.0.82 or later. Update Group-Office to version 26.0.5 or later.
