CVE-2026-73651Public exploitNetwork attack vector

Arbitrary code execution via template-literal interpolation

Published Aug 13, 2026 · Updated Aug 13, 2026

Code injection in TypeORM before 0.3.31 and 1.0.0 through 1.0.x allows remote authenticated users to execute arbitrary JavaScript. MigrationGenerateCommand.ts places introspected COMMENT, DEFAULT, and other schema strings inside template literals while escaping backticks but not ${...}. Exploitation requires schema write access and a developer or CI job to generate and load the migration, granting code execution on that host.
