Detailsinfo

A vulnerability, which was classified as problematic, was found in TypeORM up to 0.3.30/1.0.x. Affected is the function generate of the file src/commands/MigrationGenerateCommand.ts of the component Migration Generate Command. The manipulation of the argument COMMENT/DEFAULT with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

TypeORM is a TypeScript and JavaScript ORM for Node.js that supports PostgreSQL, MySQL, MariaDB, SQLite, SQL Server, Oracle, and other databases. Prior to versions 0.3.31 and 1.1.0, typeorm migration:generate embeds database schema metadata into JavaScript or TypeScript template literals in src/commands/MigrationGenerateCommand.ts, escaping backticks but not ${...} interpolation. An attacker with database schema write access can place a payload in column COMMENT or DEFAULT metadata, or another introspected schema string, and the JavaScript engine evaluates the payload when the generated migration is loaded through migration:run, import, or require. This issue is fixed in versions 0.3.31 and 1.1.0.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-73651 since 08/13/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Additional levels of successful authentication are necessary for exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1059.

Upgrading to version 0.3.31 or 1.1.0 eliminates this vulnerability.
