CVE-2026-26218
📋 TL;DR
CVE-2026-26218 allows unauthenticated attackers to gain administrative control of newbee-mall applications by using predictable default passwords on pre-seeded administrator accounts. This affects deployments that initialize or reset databases using the provided schema without changing default credentials. The vulnerability enables complete compromise of the application.
💻 Affected Systems
- newbee-mall
📦 What is this software?
Newbee Mall by Newbee Mall Project
⚠️ Risk & Real-World Impact
Worst Case
Complete administrative takeover of the application, allowing data theft, modification, deletion, and potential lateral movement to other systems.
Likely Case
Attackers gain administrative privileges, modify content, steal customer data, and potentially deploy malware or backdoors.
If Mitigated
No impact if default credentials are changed during deployment or if proper access controls prevent external access.
🎯 Exploit Status
Exploitation requires only knowledge of default credentials and access to the login interface.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not applicable - configuration issue
Vendor Advisory: https://github.com/newbee-ltd/newbee-mall/issues/119
Restart Required: No
Instructions:
1. Identify all newbee-mall deployments. 2. Check database for default administrator accounts. 3. Change all default passwords to strong, unique credentials. 4. Remove or disable unused default accounts.
🔧 Temporary Workarounds
Change Default Credentials
allModify all default administrator passwords in the database
UPDATE users SET password = 'new_secure_hash' WHERE username = 'admin' AND password = 'default_hash';
Network Access Control
linuxRestrict access to administrative interfaces using firewall rules
iptables -A INPUT -p tcp --dport 8080 -s trusted_network -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
🧯 If You Can't Patch
- Implement multi-factor authentication for all administrative accounts
- Deploy web application firewall with credential stuffing protection
🔍 How to Verify
Check if Vulnerable:
Attempt to log in to the administrative interface using known default credentials (check GitHub issue for specifics)
Check Version:
Check application configuration files or database for default credential usage
Verify Fix Applied:
Verify default credentials no longer work and all administrative accounts have strong, unique passwords
