Vvveb database accessible to attackers for stealing customer data and admin passwords

CVE advisorySeverity: CRITICAL (CVSS 9.2)

CVE-2026-41930

Vvveb uses preset database passwords that allow an external attacker to access the system's management interface. This exposes sensitive customer information and administrator accounts to theft or manipulation, risking complete application compromise.

Halo Surface Signal score for CVE-2026-41930

The vulnerability involves a bundled database management interface (phpMyAdmin). These tools are intended for administrative purposes and are typically secured behind internal controls. While they may be reachable from the internet in some misconfigured or default deployments, they are not primarily designed as public-facing services.

Horizon Alert

Summary of the vulnerability and why it matters

This vulnerability allows unauthenticated attackers to access sensitive database information, including customer details and administrator credentials. The issue arises from hard-coded credentials within the Vvveb application's configuration for phpMyAdmin, a database management tool. This could lead to account takeover and data manipulation.

  • Data Breach Risk: Customer PII and order data can be exposed.
  • Admin Account Takeover: Access to administrator password hashes enables unauthorized control.
  • Database Manipulation: Full read and write access to the database is granted.

Attack Path

How an attacker could exploit the issue

An unauthenticated attacker can exploit this by directly connecting to the exposed phpMyAdmin port on a vulnerable Vvveb instance. This provides immediate access to the database, allowing the attacker to steal sensitive information and compromise user accounts.

  • Unauthenticated network access.
  • Targets bundled phpMyAdmin.
  • Default configuration exposes credentials.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability allows unauthenticated attackers to access a database management tool with pre-configured credentials, potentially leading to a full compromise of sensitive data. While the vulnerability is significant, its actual weaponization depends on whether the affected application is exposed to the internet with the default configuration.

  • Hard-coded credentials.
  • Database access granted.
  • Vulnerability discovered recently.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

Prioritize isolating or taking offline any Vvveb services using the vulnerable docker-compose-apache.yaml configuration. The hard-coded credentials in phpMyAdmin grant unauthenticated attackers full database access, enabling data theft and account takeover. Acknowledge that no patch is currently available for this specific vulnerability.

  • Block access to phpMyAdmin port.
  • Monitor database for suspicious activity.
  • Update Vvveb to version 1.0.8.2 or later.

Frequently asked questions

What is Vvveb and what is its function related to database management?

Vvveb is a software component that includes a bundled phpMyAdmin tool. This tool is used for managing databases, allowing users to interact with and control their Vvveb databases for storing website content or application data.

What type of weakness does CVE-2026-41930 represent in Vvveb?

CVE-2026-41930 is a hard-coded credentials vulnerability. This means Vvveb uses pre-set, unchanging passwords in its configuration files for accessing its bundled phpMyAdmin tool. These discoverable credentials can allow unauthorized access to the database.

How can an attacker gain unauthorized access to Vvveb's database?

An attacker can exploit this vulnerability by connecting to the phpMyAdmin port of a vulnerable Vvveb instance. This provides unrestricted read and write access to the entire Vvveb database, including administrator password hashes and customer personally identifiable information, enabling account takeover and data manipulation. The attack vector is network-based and requires no authentication.

What is the relevance of the Halo Surface Signal score for CVE-2026-41930?

The Halo Surface Signal score is 'Possible' with a score of 3. This indicates that while the vulnerability involves a bundled database management interface (phpMyAdmin), which is typically internal, it could be reachable from the internet in misconfigured deployments. This potential external reachability makes it a noteworthy concern.

What are the recommended steps to address the Vvveb database vulnerability?

It is recommended to isolate or take offline any Vvveb services using the vulnerable configuration. Blocking access to the phpMyAdmin port and monitoring the database for suspicious activity are crucial. Users should update Vvveb to version 1.0.8.2 or later for a permanent fix, as no patch is currently available for this specific vulnerability.
