CVE-2026-40550

mpGabinet is vulnerable to Privilege Escalation due to excessive database privileges assigned to the user used by the application. An attacker with access to any running application instance connected to the backend server can extract database credentials from the application’s memory by inspecting the running process. While ability to retrieve credentials from memory is expected behavior, the exposed credentials grant administrative access to the database, exceeding the privileges required for normal application functionality. This allows an attacker to perform actions beyond those permitted through the application interface. This issue affects mpGabinet version 23.12.19 and below.
