Hyperterse: Raw exposure of database statements in MCP search tool

Moderate severity GitHub Reviewed Published Mar 12, 2026 in hyperterse/hyperterse • Updated Mar 12, 2026

Package

npm hyperterse (npm)

Affected versions

>= 2.0.0, < 2.2.0

Patched versions

2.2.0

Description

Hyperterse allows users to specify database queries for tools to execute under the hood. As of v2.0.0, there are only two tools exposed - search and execute.

The search tool allows LLMs to search for tools using natural language. While returning results, Hyperterse also returned the raw SQL queries, exposing statements which were supposed to be executed under the hood, and protected from being displayed publicly.

This issue has been fixed as of v2.2.0 and relevant tests to catch these have been added.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
