How to Fix CVE-2019-11069

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

sequelize fixed: 5.3.0 
npm install sequelize@5.3.0
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 sequelize

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-11069, inspect your project dependencies using npm:

npm ls sequelize

Analyze the terminal output to locate any version of Sequelize in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.3.0), your application is affected.

Note: The npm ls sequelize 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Sequelize, 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

Versions of `sequelize` prior to 5.3.0 (excluding v3 and v4) are vulnerable to SQL Injection. PostgreSQL option`standard_conforming_strings` is not set to `on` by default, which may allow attackers to inject SQL statements due to poor handling of backslashes in string literals. ## Recommendation Upgrade to version 5.3.0 or later.
