Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Comarch ERP Optima client uses a single high-privileged database account for all connections regardless of which application account a user authenticates with. A local attacker who can control the client process can perform memory dumping to extract these hardcoded privileged credentials and use them for unauthorized database access. The attack is possible even without an active user session, as long as the client application has been configured.

MitigationUpgrade Comarch ERP Optima client to version 2026.4 or later. As a compensating control, restrict physical and process-level access to machines running the client and implement database access segmentation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Comarch ERP Optima client is installed
    Look for Comarch ERP Optima in installed programs list (Windows: Control Panel > Programs and Features, or check C:\Program Files\Comarch or C:\Program Files (x86)\Comarch directories)
    Affected if Comarch ERP Optima client is present on the system
  2. Determine the installed version
    Right-click the Comarch ERP Optima executable (typically Optima.exe or similar) and view Properties > Details, or check the application's About/Help section
    Affected if The installed version is earlier than 2026.4
  3. Check if the client has been configured with database connection
    Look for configuration files in the application data folder (typically in %APPDATA%\Comarch or %PROGRAMDATA%\Comarch) for connection configuration files or settings that include database server details
    Affected if Configuration files exist indicating the client was set up with a database connection
  4. Verify if the client process or service runs with elevated privileges
    Open Task Manager or use tasklist /v command to check if Comarch ERP Optima processes run under a privileged account
    Affected if The client process runs under a service account or privileged user context
  5. Audit physical and process access to machines with the client
    Review who has local administrator rights or physical access to machines with Comarch ERP Optima installed; check for memory dumping tools or unauthorized access attempts
    Affected if Multiple users have administrative access or unrestricted physical access to machines running the client

The environment is affected if Comarch ERP Optima client version earlier than 2026.4 is installed and has been configured with database connections, especially on systems with shared or insufficiently restricted access.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Comarch ERP Optima client to version 2026.4 or later. As a compensating control, restrict physical and process-level access to machines running the client and implement database access segmentation.

Recommended fix Moderate confidence

2026.4

  1. Verify the current installed version of Comarch ERP Optima by checking the application or system information
  2. Ensure a complete backup of the current database and configuration is performed before upgrading
  3. Obtain the Comarch ERP Optima version 2026.4 or later from official Comarch distribution channels
  4. Perform the upgrade installation following standard Comarch ERP Optima upgrade procedures
  5. After upgrade, verify that the application now correctly uses the application user account for database connections rather than a high-privileged account
  6. Confirm the client can connect to the database successfully with the proper user-level credentials
