CVE-2026-1194: MineAdmin Information Disclosure Flaw

CVE-2026-1194 Overview

A security flaw has been discovered in MineAdmin 1.x/2.x affecting an unknown function of the Swagger component. The manipulation results in information disclosure, allowing attackers to potentially access sensitive data through the exposed API documentation interface. The attack may be performed remotely without authentication, making it a concern for any publicly accessible MineAdmin deployment. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Critical Impact

Unauthenticated remote attackers can exploit the Swagger component to disclose sensitive information from MineAdmin deployments, potentially exposing internal API structures, endpoints, and configuration details.

Affected Products

• MineAdmin 1.x
• MineAdmin 2.x

Technical Details for CVE-2026-1194

Vulnerability Analysis

This vulnerability is classified as CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The Swagger component in MineAdmin versions 1.x and 2.x contains an information disclosure flaw that can be exploited remotely over the network. Swagger is commonly used for API documentation and testing, and when improperly configured or secured, it can expose sensitive internal details about the application's API structure, endpoints, parameters, and potentially authentication mechanisms.

The vulnerability does not require authentication or user interaction to exploit, making it accessible to any attacker who can reach the affected MineAdmin instance over the network. While the confidentiality impact is limited, the exposed information could be leveraged for further reconnaissance or to identify additional attack vectors.

Root Cause

The root cause stems from improper access controls on the Swagger component within MineAdmin. The API documentation interface appears to be accessible without proper authentication or authorization checks, allowing unauthorized users to view sensitive information about the application's internal API structure. This is a common misconfiguration where development or debugging interfaces are inadvertently exposed in production environments.

Attack Vector

The attack is performed remotely over the network by accessing the Swagger component endpoint. An attacker can simply navigate to the Swagger UI or API documentation endpoint of a vulnerable MineAdmin instance to retrieve sensitive information about the application's API structure. No special tools, authentication, or complex exploitation techniques are required—the vulnerability can be exploited through a standard web browser.

The publicly available exploit demonstrates how attackers can directly access the exposed Swagger documentation to enumerate API endpoints, understand request/response structures, and identify potential authentication or authorization weaknesses in the underlying application. For technical details, see the GitHub Issue Discussion.

Detection Methods for CVE-2026-1194

Indicators of Compromise

• Unusual access patterns to Swagger-related endpoints (e.g., /swagger, /api-docs, /swagger-ui)
• Multiple requests from unknown external IP addresses to API documentation paths
• Log entries showing access to API specification files from unauthenticated sessions

Detection Strategies

• Monitor web server access logs for requests to Swagger or API documentation endpoints from external sources
• Implement alerting on high-volume requests to /swagger* or /api-docs* paths
• Review authentication logs to identify unauthenticated access to sensitive administrative endpoints

Monitoring Recommendations

• Deploy web application firewall (WAF) rules to detect and alert on Swagger endpoint enumeration attempts
• Enable detailed logging for all API documentation and administrative interface access
• Conduct regular security scans to identify exposed Swagger interfaces across your infrastructure

How to Mitigate CVE-2026-1194

Immediate Actions Required

• Restrict access to Swagger UI and API documentation endpoints to authorized users only
• Implement network-level controls (firewall rules, IP whitelisting) to limit access to administrative interfaces
• Disable Swagger in production environments if not required for operational purposes
• Review and audit all publicly accessible endpoints in MineAdmin deployments

Patch Information

No official patch information is currently available from the vendor. According to the vulnerability disclosure, the vendor was contacted early about this issue but did not respond. Organizations using MineAdmin should implement the workarounds below until an official fix is released. For more information, refer to the VulDB entry #341779.

Workarounds

• Disable the Swagger component entirely in production deployments if API documentation is not required
• Implement authentication requirements for accessing the Swagger UI and API documentation
• Use reverse proxy configurations to block external access to Swagger endpoints
• Consider migrating to an alternative administration panel solution if the vendor remains unresponsive

# Example: Block Swagger endpoints using nginx
location ~ ^/(swagger|api-docs) {
    deny all;
    return 403;
}

# Or restrict to internal networks only
location ~ ^/(swagger|api-docs) {
    allow 10.0.0.0/8;
    allow 192.168.0.0/16;
    deny all;
}
