CVE-2026-112030: Diem CMF default administrator credentials when database password is empty

CVE-2026-112030 · Severity: medium · CVSS 6.3 · Published 2026-10-19

Diem is a content management framework that generates sites from configuration files. When Diem is installed with an empty database password, the setup process automatically creates a super-administrator account with the username "admin" and password "admin". An attacker with network access to an affected installation can log in using these default credentials and gain complete administrative control over the system, including user management, content editing, configuration changes, and media handling.

Vendors: Diem-Project.

How to fix

Ensure the database connection password is set to a non-empty value before running the initial data-loading/install command. Alternatively, restrict network access to the administration login page until the default super-administrator account has been deleted or its credentials changed after installation.

Technical details

The vulnerability exists in dmCorePlugin/lib/data/dmDataLoad.php where the data loader derives the initial super-administrator password from the database connection password; when that password is empty, it falls back to the hardcoded string "admin" for both username and password. The attack requires no authentication or special conditions beyond network access to the setup process; an attacker can remotely authenticate with known default credentials on any fresh installation that completed setup with an empty database password. A fix has not been released as of the advisory date.
