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 makes use of a hard-coded password for a database user. These credentials cannot be changed. It is possible for a remote attacker to gain an access to the database with elevated privileges including executing system commands on a server. 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 · moderate confidence

Comarch ERP Optima client contains a hard-coded database password that cannot be changed by administrators. This allows a remote attacker who obtains the credentials to access the database with elevated privileges and execute system commands on the underlying server.

MitigationUpgrade Comarch ERP Optima to version 2026.4 or later where the hard-coded credentials have been removed and proper credential management implemented.

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 Comarch ERP Optima client version
    Locate the installed Comarch ERP Optima client application and check its version information, typically found in the application About dialog, installation directory metadata, or Windows Programs and Features. Compare the installed version to the affected range (versions prior to 2026.4).
    Affected if The installed version is earlier than 2026.4, as versions prior to this release contain the hardcoded database user password vulnerability.
  2. Locate database connection configuration
    Find the configuration files or registry entries that store database connection parameters for the Comarch ERP Optima client, which typically include database server address, username, and password.
    Affected if A database user account is hardcoded in the configuration with a password that cannot be modified through administrative interfaces.
  3. Verify database user password changeability
    Attempt to access administrative or configuration settings within Comarch ERP Optima that manage database credentials. Check if there is an option to modify the password for the database user account.
    Affected if The database user password cannot be changed through the application's administrative or configuration settings, indicating it is hardcoded.
  4. Inspect database user accounts
    Using database administrative tools, list user accounts configured for the Comarch ERP Optima database and check for any accounts that appear to be application-specific with non-expiring or static passwords.
    Affected if A database user account exists that was not created by administrators and has privileges beyond standard application requirements.

The environment is affected if Comarch ERP Optima client version is earlier than 2026.4 and contains a database user with a hardcoded, non-modifiable password.

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

Upgrade Comarch ERP Optima to version 2026.4 or later where the hard-coded credentials have been removed and proper credential management implemented.

Recommended fix High confidence

2026.4

  1. Upgrade Comarch ERP Optima to version 2026.4 or later as specified in the official fix description
  2. After upgrading, verify that the hard-coded credentials have been removed from the application
  3. Review database access logs to check for any unauthorized access attempts that may have occurred prior to the upgrade
  4. Ensure that database credentials are now configurable and follow proper credential management practices
  5. Test that database connectivity and elevated privileges functionality work correctly after the upgrade
