How to Fix CVE-2020-7619

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

get-git-data fixed: Latest secure release 
npm install get-git-data@Latest secure release
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 get-git-data

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-7619, inspect your project dependencies using npm:

npm ls get-git-data

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

Note: The npm ls get-git-data 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-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Get git data, 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

get-git-data through 1.3.1 is vulnerable to Command Injection. It is possible to inject arbitrary commands as part of the arguments provided to get-git-data.
