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.

GHSA-5hh8-q8hv-fr38jackson-databind has @JsonView bypass for setterless creator properties2026-06-23ghsa · osvUS
## Summary 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. ## Impact View-restricted (e.g. admin-only) setterless collection/map properties can be written from untrusted JSON despite `@JsonView` gating — an access-control / mass-assignment bypass. No RCE or DoS. ## Affected / Patched (verified via `git tag --contains`) - 2.21 line: `>= 2.21.0, < 2.21.4` -> fixed in **2.21.4** (backport `94c5d21`, #5970) - 3.x line: `>= 3.0.0, < 3.1.4` -> fixed in **3.1.4** (#5969, `5bf23ed`) ## Severity / CWE Maintainer: minor. Reporter: HIGH. CWE-863 (Incorrect Authorization); related CWE-1220. ## Credits Omkhar Arasaratnam (@omkhar) - finder.
