Background
Sequelize is an Object-Relational Mapping (ORM) library for Node.js that provides easy access to databases by mapping database entries to JavaScript objects. It is widely used for building applications that interact with databases. However, versions of Sequelize prior to 3.20.0 are vulnerable to a SQL injection attack.
Vulnerability Detail
The vulnerability in Sequelize arises from the improper handling of arrays, which are cast to strings without proper escaping. This allows an attacker to inject malicious SQL code into the query, potentially leading to unauthorized access, data manipulation, or even deletion of records. The vulnerability affects PostgreSQL, SQLite, and Microsoft SQL Server databases.
How To Fix
Latest published version: 6.37.8 as of 23 Oct 2026
npm install sequelize@6.37.8Upgrading to it may include breaking changes; the version below is the minimum fixed release for this vulnerability.
If you need the minimum change
3.20.0
This is the first release that contains the fix.

Workaround
If updating Sequelize is not immediately feasible, a temporary workaround is to manually sanitize and escape user input before using it in queries. This can be done by using prepared statements or parameterized queries provided by the database driver.
Conclusion
The SQL injection vulnerability in Sequelize can have serious security implications, allowing attackers to manipulate or delete data in the database. It is crucial to update to the latest version of Sequelize or apply the recommended workaround to mitigate the risk. For further support on vulnerability remediation, you can contact DevNack.com.
