What is CVE-2026-73651?
CVE-2026-73651 is a medium-severity code injection vulnerability in typeorm, published on 13 Aug 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
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.
Weakness: CWE-94
