CVE-2026-54517 - jackson-databind: @JsonView bypass for setterless creator properties

CVE ID :CVE-2026-54517
Published : June 23, 2026, 8:47 p.m. | 4 hours, 53 minutes ago
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.
Severity: 5.3 | MEDIUM
