CVE-2026-14471 in MCP Gateway Registry
Summary
by MITRE • 07/07/2026
Improper Neutralization of Special Elements in the metrics-service retention policy management component in Amazon mcp-gateway-registry before 1.0.13 might allow an authenticated remote user to execute arbitrary SQL queries via a crafted table_name value that is interpolated into SQL statements in identifier position.
To remediate this issue, users should upgrade to version 1.0.13 or later.

This vulnerability resides within the metrics-service retention policy management component of Amazon mcp-gateway-registry software, specifically affecting versions prior to 1.0.13. The flaw represents a classic sql injection vulnerability that occurs when user-supplied input is improperly handled during database query construction. The vulnerability manifests when a crafted table_name value is passed through the system and subsequently interpolated into sql statements at an identifier position rather than being properly parameterized. This improper handling creates an avenue for authenticated remote attackers to manipulate database queries and execute arbitrary sql commands.
The technical implementation of this vulnerability falls under the category of cwe-94, which encompasses code injection flaws, specifically sql injection when dealing with database operations. The issue stems from insufficient input validation and sanitization within the retention policy management functionality where user-provided table names are directly incorporated into sql query structures without proper escaping or parameterization mechanisms. This design flaw allows malicious actors who have authentication credentials to manipulate the system's database interactions by crafting specific table_name values that when processed, result in unauthorized sql command execution.
From an operational impact perspective, this vulnerability enables authenticated remote code execution against the affected database system through sql injection attacks. Attackers can leverage this weakness to perform data exfiltration, modify retention policies, access sensitive information stored within the metrics-service database, or potentially escalate privileges within the database environment. The authentication requirement reduces the attack surface compared to unauthenticated vulnerabilities but still presents a significant risk since legitimate users with access credentials could be compromised through credential theft or insider threats. The vulnerability affects organizations relying on proper data retention management for compliance and operational requirements.
The remediation strategy involves upgrading to version 1.0.13 or later of the mcp-gateway-registry software, which implements proper input sanitization and parameterization techniques to prevent sql injection attacks. Organizations should also implement additional security controls such as least privilege access for database users, regular security assessments of sql query construction patterns, and monitoring for unusual database activity that might indicate exploitation attempts. The fix aligns with recommended security practices from the mitre corporation's attack technique framework where this vulnerability would map to techniques involving sql injection and command execution through database interfaces. Security teams should conduct thorough testing after applying the patch to ensure no regressions in functionality while verifying that the sql injection mitigation is properly implemented across all affected components of the metrics-service retention policy management system.
