CVE-2026-54517 (GCVE-0-2026-54517)

Vulnerability from cvelistv5 – Published: 2026-06-23 20:47 – Updated: 2026-06-24 19:13

Title

jackson-databind: @JsonView bypass for setterless creator properties

Summary

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)
