SQL Injection in sequelize

Critical severity GitHub Reviewed Published Oct 25, 2019 to the GitHub Advisory Database • Updated Sep 11, 2023

Package

npm sequelize (npm)

Affected versions

< 4.44.3
>= 5.0.0, < 5.15.1

Patched versions

4.44.3
5.15.1

Description

Affected versions of sequelize are vulnerable to SQL Injection. The function sequelize.json() incorrectly formatted sub paths for JSON queries, which allows attackers to inject SQL statements and execute arbitrary SQL queries if user input is passed to the query. Exploitation example:

return User.findAll({
  where: this.sequelize.json("data.id')) AS DECIMAL) = 1 DELETE YOLO INJECTIONS; -- ", 1)
});

Recommendation

If you are using sequelize 5.x, upgrade to version 5.15.1 or later.
If you are using sequelize 4.x, upgrade to version 4.44.3 or later.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
