GHSA-8CW5-3V42-MC6R

Vulnerability from github – Published: 2026-05-14 12:30 – Updated: 2026-05-14 12:30

Details

Comarch ERP Optima client connects to a database using a high privileged account regardless of an application account to which a user logs in. It is possible for a local attacker who controls the client process to dump it's memory, extract credentials and use them to gain a privileged access to the database. In order to exploit this vulnerability, the client application has to be already configured, but a user does not have to be logged in. This issue has been fixed in version 2026.4

Severity

7.5 (High)
