How to Fix CVE-2025-9654

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

@aiondadotcom/mcp-ssh fixed: 1.1.0 
npm install @aiondadotcom/mcp-ssh@1.1.0
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 @aiondadotcom/mcp-ssh

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-9654, inspect your project dependencies using npm:

npm ls @aiondadotcom/mcp-ssh

Analyze the terminal output to locate any version of @aiondadotcom/mcp ssh in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.1.0), your application is affected.

Note: The npm ls @aiondadotcom/mcp-ssh 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 @aiondadotcom/mcp ssh, 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 security flaw has been discovered in AiondaDotCom mcp-ssh up to 1.0.3. Affected by this issue is some unknown functionality of the file server-simple.mjs. Performing manipulation results in command injection. The attack can be initiated remotely. Upgrading to version 1.0.4 and 1.1.0 can resolve this issue. The patch is named cd2566a948b696501abfa6c6b03462cac5fb43d8. It is advisable to upgrade the affected component.
