CVE-2026-54517 Details
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.
A vulnerability in Jackson Databind allows JsonView annotations to be bypassed for setterless collection or map properties, leading to unauthorized data deserialization. This issue affects Jackson Databind versions 2.21.0 prior to 2.21.4 and 3.0.0 prior to 3.1.4. The vulnerability arises because the active-view filter is only applied to creator properties, not to regular properties. As a result, setterless collections annotated with restrictive JsonView can be populated from untrusted JSON, even when the active view should exclude them.
Users can upgrade to Jackson Databind versions 2.21.4 or 3.1.4 to address this vulnerability.
