npm ls danger

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2026-16629, inspect your project dependencies using npm:

npm ls danger

Analyze the terminal output to locate any version of Danger in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 13.0.8), your application is affected.

Note: The npm ls danger 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 Danger, 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 identified in danger danger-js up to 13.0.7. Impacted is the function danger.git.diffForFile of the file source/platforms/git/localGetFileAtSHA.ts of the component CLI. Such manipulation of the argument File leads to os command injection. The attack needs to be performed locally. Upgrading to version 13.0.8 is recommended to address this issue. The name of the patch is 087a7290264cc6fb7154ea8c2552a7b2cb8b33a3. It is advisable to upgrade the affected component.
