How to Fix CVE-2026-31841

To remediate this vulnerability, upgrade all affected Hyperterse dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

hyperterse fixed: 2.2.0 
npm install hyperterse@2.2.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls hyperterse

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-31841, inspect your project dependencies using npm:

npm ls hyperterse

Analyze the terminal output to locate any version of Hyperterse in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.2.0), your application is affected.

Note: The npm ls hyperterse command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-433: Unparsed Raw Web Content Delivery, where the product stores raw content or supporting code under the web document root with an extension that is not specifically handled by the server. In Hyperterse, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Hyperterse allows users to specify database queries for tools to execute under the hood. As of [v2.0.0](https://github.com/hyperterse/hyperterse/releases/tag/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](https://github.com/hyperterse/hyperterse/releases/tag/v2.2.0) and relevant tests to catch these have been added.
