In BeanDeserializer._deserializeUsingPropertyBased, the active-view (@JsonView) filter was applied only to creator properties; the regular property-buffering branch performed no prop.visibleInView(activeView) check. A change making SetterlessProperty.isMerging() return true routed setterless Collection/Map properties through this unguarded path, so a setterless collection annotated with a restricted @JsonView is populated from attacker JSON even when the active view excludes it.
View-restricted (e.g. admin-only) setterless collection/map properties can be written from untrusted JSON despite @JsonView gating — an access-control / mass-assignment bypass. No RCE or DoS.
