CVE-2026-27832 | Group-Office is an enterprise customer relationship management and groupware tool.

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.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') 🎯 High

The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as…

🛡️ Empfohlene Mitigation: Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482]. For example, consider using persistence layers such as Hibernate or Enterprise Java Beans, which can provide significant protection against SQL injection if used proper…
