Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')


Severity High
Score 9.8/10


Sequelize is a Node.js ORM tool. In versions through 6.19.0, and 7.0.0-alpha.1 through 7.0.0-alpha.9, a SQL injection exploit exists related to replacements. Parameters that are passed through replacements are not properly escaped which can lead to arbitrary SQL injection depending on the specific queries in use. Users are advised to upgrade. Users unable to upgrade should not use the `replacements` and the `where` option in the same query.

CWE-89 - SQL Injection

Structured Query Language (SQL) injection attacks are one of the most common types of vulnerabilities. They exploit weaknesses in vulnerable applications to gain unauthorized access to backend databases. This often occurs when an attacker enters unexpected SQL syntax in an input field. The resulting SQL statement behaves in the background in an unintended manner, which allows the possibility of unauthorized data retrieval, data modification, execution of database administration operations, and execution of commands on the operating system.
