Admin-level SQL execution via unrestricted query input

Published Aug 14, 2026 · Updated Aug 14, 2026

SQL injection in emlog 2.6.20 and earlier allows remote authenticated users to execute arbitrary SQL through the AI tool endpoint. admin/ai.php decodes the POSTed params JSON and passes its sql value to Ai::queryDatabase without restricting statement types, tables, or dangerous SQL constructs. An administrator session is required; successful requests can read password records and can modify or delete the application database.
