CVE-2026-30951: Sequelize is a Node.js ORM tool
CVE-2026-30951 is a high-severity flaw (CVSS 7.5) affecting sequelize. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- High severity
- Public exploit reference
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
