Doc Text:	A flaw was found in jackson-databind. A remote attacker can exploit this vulnerability due to an issue in how active-view (@JsonView) filters are applied. Specifically, setterless collections annotated with a restricted @JsonView can be populated from attacker-controlled JSON even when the active view is configured to exclude them. This can lead to information disclosure, allowing an attacker to access data that should otherwise be restricted.	Story Points:	---

Description OSIDB Bzimport 2026-06-23 22:01:33 UTC

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.
