CVE-2026-41930 is a critical vulnerability in givanz Vvveb prior to version 1.0.8.2 caused by hard-coded credentials in the docker-compose-apache.yaml file. This misconfiguration exposes the phpMyAdmin container without authentication, allowing unauthenticated attackers to connect directly to the database management interface. Attackers can then read and modify the entire database contents, including sensitive data such as administrator password hashes and customer personal information. The vulnerability stems from missing authentication controls on a critical function (CWE-306). The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No official fix or patch has been published yet.

Exploitation of this vulnerability allows unauthenticated attackers to gain full read and write access to the Vvveb database via phpMyAdmin. This includes access to administrator credentials, customer personally identifiable information, and order data. The impact includes potential account takeover, data theft, and data manipulation, severely compromising the confidentiality, integrity, and availability of the affected system.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should avoid deploying vulnerable versions of Vvveb or restrict network access to the phpMyAdmin container to trusted users only. Removing or modifying the docker-compose-apache.yaml configuration to eliminate hard-coded credentials or disable the exposed phpMyAdmin service can mitigate the risk. Monitor vendor channels for updates and apply official patches once released.
