Description

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.
