How to Fix CVE-2026-5831

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

taskflow-ai fixed: 2.1.9 
npm install taskflow-ai@2.1.9
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 taskflow-ai

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-5831, inspect your project dependencies using npm:

npm ls taskflow-ai

Analyze the terminal output to locate any version of Taskflow ai in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1.9), your application is affected.

Note: The npm ls taskflow-ai 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-77: Improper Neutralization of Special Elements used in a Command ('Command Injection'), where the product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component. In Taskflow ai, 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 Agions taskflow-ai up to 2.1.8. This impacts an unknown function of the file src/mcp/server/handlers.ts of the component terminal_execute. Performing a manipulation results in os command injection. The attack is possible to be carried out remotely. Upgrading to version 2.1.9 will fix this issue. The patch is named c1550b445b9f24f38c4414e9a545f5f79f23a0fe. Upgrading the affected component is recommended. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.
