Detailsinfo

A vulnerability classified as critical was found in Intermesh groupoffice up to 6.8.152/25.0.86/26.0.7. Affected by this vulnerability is some unknown processing of the file index.php?r=email/template/emailSelection of the component Endpoint. The manipulation of the argument advancedQueryData with an unknown input leads to a sql injection vulnerability. The CWE definition for the vulnerability is 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-27832 since 02/24/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1505 for this issue.

Upgrading to version 6.8.153, 25.0.87 or 26.0.8 eliminates this vulnerability.
