sequelize is an Object-relational mapping, or a middleman to convert things from Postgres, MySQL, MariaDB, SQLite and Microsoft SQL Server into usable data for NodeJS In Postgres, SQLite, and Microsoft SQL Server there is an issue where arrays are treated as strings and improperly escaped. This causes potential SQL injection in sequelize 3.19.3 and earlier, where a malicious user could put `["test", "'); DELETE TestTable WHERE Id = 1 --')"]` inside of ``` database.query('SELECT * FROM TestTable WHERE Name IN (:names)', { replacements: { names: directCopyOfUserInput } }); ``` and cause the SQL statement to become `SELECT Id FROM Table WHERE Name IN ('test', '\'); DELETE TestTable WHERE Id = 1 --')`. In Postgres, MSSQL, and SQLite, the backslash has no special meaning. This causes the the statement to delete whichever Id has a value of 1 in the TestTable table.

sequelize SQL注入漏洞

sequelize是一个用于Node.js的数据库ORM（对象关系映射）工具。 sequelize 3.19.3及之前版本中存在SQL注入漏洞，该漏洞源于程序将数组用作字符串而却没有正确的对其进行编码。攻击者可利用该漏洞删除TestTable表单中带有1的ID。
