The emreguo/mcp-shodan package integrates the Model Context Protocol with Shodan’s database, allowing AI assistants to query threat intelligence. However, vulnerabilities in handling upstream API responses and inadequate input validation can lead to improper error handling conditions. When external endpoints return unexpected structures or error codes, the application layer may fail to sanitize inputs or handle exceptions cleanly. This oversight creates vectors for improper validation, potentially leading to application instability, unhandled exceptions, or information exposure under specific malformed query parameters. Attackers can leverage these edge-case input vectors to probe application reliability or trigger denial-of-service conditions within the MCP server runtime environment. Ensuring strict type checking and robust error boundaries is essential to maintaining stable operations across connected AI tools. Proper exception handling prevents upstream service anomalies from propagating downstream to the client interface.
DailyCVE Form:
Platform: mcp-shodan
Version: 0.7
Vulnerability : API Flaw
Severity: Medium
date: 2026-10-20
Prediction: 2026-10-27
What Undercode Say:
To verify and inspect the package release behavior, developers can utilize standard environment setup and build commands for the TypeScript-based MCP server implementation.
git clone https://github.com/emreguo/mcp-shodan.git cd mcp-shodan npm install npm run build export SHODAN_API_KEY="your-api-key-here" npm start
Exploit: (Educational Purposes!)
Attackers targeting integration flaws typically supply malformed payloads or invalid parameter structures to trigger unhandled promise rejections or application crashes within the server runtime.
// Example probe for unhandled error conditions in MCP parameters
async function testVulnerability() {
const payload = { cve: "INVALID-FORMAT-12345", strict: true };
try {
await queryShodanCVEDB(payload);
} catch (error) {
console.log("Captured unhandled exception state:", error);
}
}
Protection: from this CVE
Users must update the emreguo/mcp-shodan package to the latest version featuring improved error handling and cache layer fixes. Always validate environment variables and sanitize input parameters before passing them to external API wrappers.
Impact:
Exploitation of this vulnerability can result in service disruptions, unhandled exceptions crashing the local MCP server instance, and potential visibility into internal traceback data during upstream communication failures.
