CVE-2026-27832
February 27, 2026
Group-Office is an enterprise customer relationship management and groupware tool. Versions prior to 26.0.8, 25.0.87, and 6.8.153 have a SQL Injection (SQLi) vulnerability, exploitable through the "advancedQueryData" parameter ("comparator" field) on an authenticated endpoint. The endpoint "index.php?r=email/template/emailSelection" processes "advancedQueryData" and forwards the SQL comparator without a strict allowlist into SQL condition building. This enables blind boolean-based exfiltration of the "core_auth_password" table. Versions 26.0.8, 25.0.87, and 6.8.153 fix the issue.
