Vvveb hard-coded credentials leak DB (CVE-2026-41930)

Patch now - CVE-2026-41930 is a critical hard-coded credentials issue in Vvveb before version 1.0.8.2 that gives unauthenticated attackers full unrestricted read and write access to the Vvveb database, including administrator password hashes and customer PII. Patched in Vvveb 1.0.8.2 - update immediately.

Overview

CVE-2026-41930 is a hard-coded credentials vulnerability in Vvveb’s docker-compose-apache.yaml configuration. The pre-configured phpMyAdmin container ships with known, static database credentials that are publicly discoverable in the source code. An unauthenticated attacker who can reach the phpMyAdmin port can log in using these credentials and gain unrestricted read and write access to the entire Vvveb database.

Impact

This vulnerability enables complete database compromise. An attacker with database access can:

• Extract administrator password hashes, enabling offline cracking and account takeover.
• Read customer PII, including names, email addresses, and order history.
• Modify or delete order data, payment statuses, and user accounts.
• Inject malicious content or backdoors into the application.
• Exfiltrate the entire customer database.

With full read and write capabilities, the attacker can essentially take over the Vvveb instance and all its data.

Affected Versions

Vvveb versions before 1.0.8.2 are vulnerable. This specifically affects deployments using the provided docker-compose-apache.yaml file.

Remediation and Mitigation

Patch: Upgrade to Vvveb version 1.0.8.2 or later.

Mitigation: If immediate patching is not possible, do the following:

1. Change the default database credentials in the docker-compose-apache.yaml file.
2. Restrict network access to the phpMyAdmin container. Do not expose it to the internet. Instead, connect only from a trusted internal network or use a secure VPN.
3. Use a separate, dedicated database server rather than the bundled phpMyAdmin container.
4. Review database access logs for any unauthorized connections.

Security Insight

CVE-2026-41930 is a textbook case of why hard-coded credentials remain one of the most dangerous vulnerabilities in containerized deployments. Unlike complex memory corruption or injection bugs, this flaw requires no skill to exploit and is trivial to discover from public source code. Developers who ship docker-compose files with default credentials effectively hand attackers the keys to their application’s backend. This incident underscores a broader industry trend: as more applications adopt Docker and Docker Compose for quick deployment, default security misconfigurations like this become critical attack surfaces that adversaries scan for at scale. For comparison, similar hard-coded credentials flaws in products like Apache ActiveMQ CVE-2026-34197 have led to active exploitation within days of disclosure. Organizations using Vvveb should prioritize this patch before automated scanning tools find exposed phpMyAdmin instances.
