CVE-2022-31106

Underscore.deep is a collection of Underscore mixins that operate on nested objects. Versions of `underscore.deep` prior to version 0.5.3 are vulnerable to a prototype pollution vulnerability. An attacker can craft a malicious payload and pass it to `deepFromFlat`, which would pollute any future Objects created. Any users that have `deepFromFlat` or `deepPick` (due to its dependency on `deepFromFlat`) in their code should upgrade to version 0.5.3 as soon as possible. Users unable to upgrade may mitigate this issue by modifying `deepFromFlat` to prevent specific keywords which will prevent this from happening.

Underscore.deep es una colección de mixins de Underscore que operan sobre objetos anidados. Las versiones de "underscore.deep" anteriores a 0.5.3 son susceptibles a una vulnerabilidad de contaminación de prototipos. Un atacante puede diseñar una carga maliciosa y pasarla a "deepFromFlat", lo que contaminaría cualquier objeto creado en el futuro. Cualquier usuario que tenga "deepFromFlat" o "deepPick" (debido a su dependencia de "deepFromFlat") en su código debería actualizar a versión 0.5.3 lo antes posible. Los usuarios que no puedan actualizarse pueden mitigar este problema al modificar "deepFromFlat" para evitar palabras clave específicas que impidan que esto ocurra
