SQL Injection in Group-Office Email Template Enables Data Exfiltration

Publication date: 2026-02-27

Last updated on: 2026-03-04

Assigner: GitHub, Inc.

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.

CWE ID Description
CWE-89 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 SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL Injection (SQLi) issue in Group-Office, an enterprise customer relationship management and groupware tool. It affects versions prior to 26.0.8, 25.0.87, and 6.8.153. The vulnerability occurs through the `advancedQueryData` parameter, specifically the `comparator` field, on an authenticated endpoint.

The endpoint `index.php?r=email/template/emailSelection` processes the `advancedQueryData` parameter and forwards the SQL comparator without a strict allowlist into SQL condition building. This improper handling allows an attacker to perform blind boolean-based exfiltration of the `core_auth_password` table.

The issue is fixed in versions 26.0.8, 25.0.87, and 6.8.153.

Impact Analysis

This SQL Injection vulnerability can allow an attacker with authenticated access to extract sensitive information from the database, specifically from the `core_auth_password` table.

Such unauthorized data exfiltration can lead to credential compromise, unauthorized access, and potential further exploitation of the system.
