CVE-2026-39178Network attack vector

Database compromise via unescaped password update

Published Jul 8, 2026 · Updated Jul 8, 2026

SQL injection in SOGo before 5.12.7 allows remote authenticated users to compromise its database through the change-password component. SQLSource.m's changePasswordForLogin method interpolates the encrypted password and login into an UPDATE string without adaptor-aware quoting. Exposure requires at least one PostgreSQL user source; successful exploitation enables mass password changes, database compromise, and server-side code execution.
