Descriptions

When the Node.js policy feature checks the integrity of a resource against a trusted manifest, the application can intercept the operation and return a forged checksum to the node's policy implementation, thus effectively disabling the integrity check.
Impacts:
This vulnerability affects all users using the experimental policy mechanism in all active release lines: 18.x and, 20.x.
Please note that at the time this CVE was issued, the policy mechanism is an experimental feature of Node.js.

Cuando la función de política de Node.js verifica la integridad de un recurso con un manifiesto confiable, la aplicación puede interceptar la operación y devolver una suma de verificación falsificada a la implementación de la política del nodo, deshabilitando así efectivamente la verificación de integridad. Impactos: esta vulnerabilidad afecta a todos los usuarios que utilizan el mecanismo de política experimental en todas las líneas de versiones activas: 18.x y 20.x. Tenga en cuenta que en el momento en que se emitió este CVE, el mecanismo de política era una característica experimental de Node.js.
