Applications using Sequelize ORM versions prior to 6.37.8 are vulnerable to SQL injection attacks through improperly escaped JSON/JSONB filtering, potentially allowing attackers to access, modify, or…. A patch is available.

Is there a public PoC exploit available for CVE-2026-30951?

Yes, a public proof-of-concept exploit is available for CVE-2026-30951. Prioritise patching immediately. EPSS: 0.0%.

How to fix or mitigate CVE-2026-30951?

Within 24 hours: Identify all Node.js applications using Sequelize and document version numbers; assess whether JSON/JSONB filtering is used in production queries. Within 7 days: Implement input validation and parameterized query patterns to avoid dynamic JSON casting; deploy WAF rules to detect SQL injection patterns in application traffic; segment database access with least-privilege credentials. Within 30 days: Upgrade to Sequelize 6.37.8 or later when available; conduct code audit of all JSON/JSONB where clause implementations; perform penetration testing on affected query paths.

DescriptionNVD

Sequelize is a Node.js ORM tool. Prior to 6.37.8, there is 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. This vulnerability is fixed in 6.37.8.

AnalysisAI

SQL injection in Sequelize prior to version 6.37.8 allows unauthenticated attackers to execute arbitrary SQL queries and extract sensitive data by manipulating JSON object keys in WHERE clause operations. The vulnerability stems from improper sanitization of cast type parameters in the _traverseJSON() function, which directly interpolates user-controlled input into CAST SQL statements. Node.js applications using affected Sequelize versions are at risk of complete database compromise.
