What is CVE-2026-30237?

Group-Office, an enterprise CRM and groupware solution, has a reflected cross-site scripting vulnerability located in its installer. This vulnerability exists in versions prior to 6.8.155, 25.0.88, and 26.0.10 due to the lack of proper escaping in the installer script, specifically in the endpoint install/license.php. Specifically, the POST field 'license' can be manipulated to execute arbitrary scripts, creating a potential for malicious exploitation. Users are advised to upgrade to the patched versions to mitigate the risk associated with this vulnerability.
