Executive Summary

CVE-2026-26218 is a critical vulnerability in newbee-mall versions up to 1.0.0 caused by default administrator accounts included in the database initialization script.

These accounts have predictable, hard-coded passwords. If the database is initialized or reset using the provided schema and the default credentials are not changed, unauthenticated attackers can log in as administrators.

This allows attackers to gain full administrative control of the application without needing any privileges or user interaction.

Detection Guidance

This vulnerability can be detected by checking if the default seeded administrator accounts with predictable passwords are present in the database initialization script or active in the system.

You can attempt to log in using the known default administrator credentials to verify if the vulnerability exists.

• Run a database query to list administrator accounts and check for default usernames.
• Attempt login via the application interface using default credentials.
