## Description

jackson-databind contains the general-purpose data-binding functionality
and tree-model for Jackson Data Processor. From 2.21.0 until 2.21.4 and
3.1.4, 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. This
vulnerability is fixed in 2.21.4 and 3.1.4.
