CVE-2026-27832Network attack vector

Authenticated password disclosure via comparator SQL injection

Published Feb 27, 2026 · Updated Feb 27, 2026

SQL injection in GroupOffice before 6.8.153, 25.0.87, or 26.0.8 allows remote authenticated users to read password data. The email template-selection endpoint passes advancedQueryData[].comparator through FindCriteria validation that accepts operator-like substrings and concatenates the value into an SQL condition. A logged-in account and network access are required; crafted boolean expressions disclose core_auth_password rows and can degrade database performance.
