How to Fix CVE-2020-7624

To remediate this vulnerability, upgrade all affected Withdrawn Advisory dependencies to a patched release.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

effect fixed: Latest secure release 
npm install effect@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 effect

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2020-7624, inspect your project dependencies using npm:

npm ls effect

Analyze the terminal output to locate any version of Withdrawn Advisory in your dependency tree.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 effect 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 In Withdrawn Advisory, software state validation or input boundaries are circumvented during processing.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

## Withdrawn Advisory This advisory has been withdrawn because the [npm package effect](https://www.npmjs.com/package/effect), for which alerts were issued, does not correspond with https://github.com/Javascipt/effect, the repository with the vulnerable code. https://github.com/Javascipt/effect is not in any [supported ecosystem](https://docs.github.com/en/code-security/security-advisories/working-with-global-security-advisories-from-the-github-advisory-database/about-the-github-advisory-database#github-reviewed-advisories). Additionally, the CVE Numbering Authority that issued the CVE for CVE-2020-7624 has updated [their advisory](https://snyk.io/vuln/SNYK-JS-EFFECT-564256) stating that "This was deemed not a vulnerability." ## Original Description effect through 1.0.4 is vulnerable to Command Injection. It allows execution of arbitrary command via the options argument.
