CVE-2026-19263

INQUIRELAB · mcp-bridge-api

The INQUIRELAB mcp-bridge-api is vulnerable to command injection, allowing unauthenticated attackers to execute arbitrary system commands.

Executive summary

A critical command injection vulnerability in INQUIRELAB mcp-bridge-api allows unauthenticated attackers to achieve remote code execution on the underlying host.

Vulnerability

The application is susceptible to command injection (CWE-77) and broader injection flaws (CWE-74). This allows an unauthenticated attacker to inject malicious commands into system processes.

Business impact

Successful exploitation allows for complete compromise of the host system, including unauthorized data access, lateral movement within the network, and potential system destruction. The CVSS score of 7.3 underscores the high risk posed to the confidentiality, integrity, and availability of the server hosting the API.

Remediation

Immediate Action: As no specific patch version is documented, users should monitor the official INQUIRELAB repository for security updates and restrict access to the API.

Proactive Monitoring: Inspect server logs for suspicious system calls or unexpected processes spawned by the API service.

Compensating Controls: Deploy a Web Application Firewall (WAF) with rules configured to detect and block common command injection patterns.

Exploitation status

Public Exploit Available: Unknown

Analyst recommendation

Due to the severity of command injection, administrators should isolate the affected service from public networks until a formal fix is released by the vendor. Rigorous input validation and the principle of least privilege should be applied to all API interactions to minimize the attack surface.
