CVE-2026-27832

Group-Office Has Authenticated SQL Injection in advancedQueryData.comparator

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 coreauthpassword table. Versions 26.0.8, 25.0.87, and 6.8.153 fix the issue.
