Security readout for executives and security teams
Plain-English summary
CVE-2026-27832 affects Intermesh Group-Office, a CRM and groupware platform. An authenticated user can abuse an email template selection feature to run unintended database logic. The reported impact is high because sensitive password-related data may be exposed. Fixed versions are available.
Executive priority
Prioritize patching in the next maintenance window, sooner for internet-facing or broadly accessible systems. The vulnerability requires login, but compromise of sensitive password-related data could create wider account and business risk.
Technical view
The flaw is CWE-89 SQL injection in the advancedQueryData comparator field on index.php?r=email/template/emailSelection. Group-Office forwarded the comparator into SQL condition building without a strict allowlist. Sources describe authenticated, blind boolean-based exfiltration of the core_auth_password table. Affected versions are before 26.0.8, 25.0.87, and 6.8.153.
Likely exposure
Exposure is limited to deployments of Intermesh Group-Office running affected versions where an attacker has a valid authenticated account. Internet-facing Group-Office portals increase business risk, but the source does not state unauthenticated exploitation.
Exploitation context
The CVSS v4.0 score is 7.1 with network access, low complexity, and low privileges required. The CVE is not listed as KEV in the provided bundle, and no cited source states active exploitation.
Researcher notes
Evidence comes from the CVE record and GitHub advisory. The bundle identifies the vulnerable parameter, endpoint, affected version ranges, CVSS vector, and fixed versions. It does not provide KEV status or confirmed exploitation in the wild.
Mitigation direction
- Upgrade Group-Office to 26.0.8, 25.0.87, or 6.8.153 or later.
- Review vendor advisory for version-specific upgrade guidance.
- Limit Group-Office access to trusted networks where practical.
- Review accounts with access to email template selection features.
Validation and detection
- Inventory all Group-Office instances and record installed versions.
- Confirm no instance runs below 6.8.153, 25.0.87, or 26.0.8.
- Check authentication logs for unusual access by low-privileged accounts.
- Review database and application logs for suspicious emailSelection activity.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
