Security Advisories 🚨

🚨 Sequelize - Default support for “raw attributes” when using parentheses

Impact

Sequelize 6.28.2 and prior has a dangerous feature where using parentheses in the attribute option would make Sequelize use the string as-is in the SQL

User.findAll({
  attributes: [
    ['count(id)', 'count']
  ]
});

Produced

SELECT count(id) AS "count" FROM "users"

Patches

This feature was deprecated in Sequelize 5, and using it prints a deprecation warning.

This issue has been patched in @sequelize/[email protected] and [email protected].

In Sequelize 7, it now produces the following:

SELECT "count(id)" AS "count" FROM "users"

In Sequelize 6, it throws an error explaining that we had to introduce a breaking change, and requires the user to explicitly opt-in to either the Sequelize 7 behavior (always escape) or the Sequelize 5 behavior (inline attributes that include () without escaping). See #15710 for more information.

Mitigations

Do not use user-provided content to build your list or attributes. If you do, make sure that attribute in question actually exists on your model by checking that it exists in the rawAttributes property of your model first.

CVE: CVE-2023-22578

🚨 Unsafe fall-through in getWhereConditions

Impact

Providing an invalid value to the where option of a query caused Sequelize to ignore that option instead of throwing an error.

A finder call like the following did not throw an error:

User.findAll({
  where: new Date(),
});

As this option is typically used with plain javascript objects, be aware that this only happens at the top level of this option.

Patches

This issue has been patched in [email protected] & @sequelize/[email protected]

🚨 Sequelize vulnerable to SQL Injection via replacements

Impact

The SQL injection exploit is related to replacements. Here is such an example:

In the following query, some parameters are passed through replacements, and some are passed directly through the where option.

User.findAll({
  where: or(
    literal('soundex("firstName") = soundex(:firstName)'),
    { lastName: lastName },
  ),
  replacements: { firstName },
})

This is a very legitimate use case, but this query was vulnerable to SQL injection due to how Sequelize processed the query: Sequelize built a first query using the where option, then passed it over to sequelize.query which parsed the resulting SQL to inject all :replacements.

If the user passed values such as

{
  "firstName": "OR true; DROP TABLE users;",
  "lastName": ":firstName"
}

Sequelize would first generate this query:

SELECT * FROM users WHERE soundex("firstName") = soundex(:firstName) OR "lastName" = ':firstName'

Then would inject replacements in it, which resulted in this:

SELECT * FROM users WHERE soundex("firstName") = soundex('OR true; DROP TABLE users;') OR "lastName" = ''OR true; DROP TABLE users;''

As you can see this resulted in arbitrary user-provided SQL being executed.

Patches

The issue was fixed in Sequelize 6.19.1

Workarounds

Do not use the replacements and the where option in the same query if you are not using Sequelize >= 6.19.1

🚨 Sequelize information disclosure vulnerability

Due to improper input filtering in the sequelize js library, can malicious queries lead to sensitive information disclosure.
