CVE-2026-73231

Faker generates massive amounts of fake data in the browser and Node.js. Prior to 10.5.0, the faker.helpers.fake method in src/modules/helpers/eval.ts allows attacker-controlled fake templates to access the Function constructor through fakeEval.resolveProperty when a function returns another function, enabling arbitrary JavaScript code execution. This issue is fixed in version 10.5.0.

Summary		(es) Faker genera cantidades masivas de datos falsos en el navegador y Node.js. Antes de la versión 10.5.0, el método faker.helpers.fake en src/modules/helpers/eval.ts permite que plantillas falsas controladas por el atacante accedan al constructor Function a través de fakeEval.resolveProperty cuyo una función devuelve otra función, lo que permite la ejecución arbitraria de código JavaScript. Este problema se corrigió en la versión 10.5.0.
