Official 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.

Technical Analysis

CVE-2026-27832 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.

From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
