How to Fix CVE-2026-2130

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

mcp-maigret fixed: 1.0.13 
npm install mcp-maigret@1.0.13
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 mcp-maigret

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-2130, inspect your project dependencies using npm:

npm ls mcp-maigret

Analyze the terminal output to locate any version of Mcp maigret in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.13), your application is affected.

Note: The npm ls mcp-maigret 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-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), where the product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. In Mcp maigret, 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

A vulnerability was determined in BurtTheCoder mcp-maigret up to 1.0.12. This affects an unknown part of the file src/index.ts of the component search_username. Executing a manipulation of the argument Username can lead to command injection. The attack may be launched remotely. Upgrading to version 1.0.13 is able to mitigate this issue. This patch is called b1ae073c4b3e789ab8de36dc6ca8111ae9399e7a. Upgrading the affected component is advised.
