Sequelize Node.js ORM tool contains a SQL injection vulnerability in versions prior to 6.37.8. The vulnerability exists in JSON/JSONB where clause processing where the _traverseJSON() function improperly handles cast types. Attackers who control JSON object keys can inject arbitrary SQL through unescaped cast types in CAST() operations. This allows data exfiltration from any table in the database. The issue is fixed in version 6.37.8.
