Vulnerabilidad crítica de contaminación de prototipos en biblioteca scim-patch anterior a v0.9.1

La biblioteca scim-patch versiones anteriores a 0.9.1 es vulnerable a contaminación de prototipos (prototype pollution) al procesar operaciones SCIM PATCH con valores malformados. Un atacante puede inyectar propiedades en Object.prototype a través de claves como "__proto__.someProp", comprometiendo todos los objetos planos en el proceso Node.js afectado. Esto afecta a servicios que procesan JSON controlado por el atacante, típicamente APIs de identidad y gestión de acceso.

@phun-ky/defaults-deep is a library like lodash defaultsDeep with array preservation and no lodash dependency. Prior to 2.0.5, defaultsDeep() recursively merges user-supplied objects without filtering proto, constructor, and prototype, allowing properties to be written to Object.prototype. This issue is fixed in version 2.0.5.
