# Missing TLS validation

## Overview

* **Rule ID**: `javascript_node_missing_tls_validation`
* **Applicable Languages**: Javascript
* **Weakness ID**: CWE-295

## Description

Neglecting to validate TLS certificates exposes your application to serious security risks, such as Man-in-the-Middle attacks and data interception. This vulnerability arises when the application does not properly verify the SSL/TLS certificate of the server it connects to, potentially allowing attackers to intercept or alter data in transit.

## Remediation Guidelines

* **Do not** disable SSL/TLS certificate validation. In particular, avoid setting the `NODE_TLS_REJECT_UNAUTHORIZED` variable to zero in security-sensitive environments. Disabling this validation compromises your application's security by leaving it open to potential attacks.

  ```javascript
  process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";

  ```
