Description

## Summary `UnwrappedPropertyHandler.processUnwrappedCreatorProperties()` replays buffered JSON into creator parameters but never consults `prop.visibleInView(activeView)`. The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses that check, so a constructor parameter annotated with both `@JsonView(AdminView.class)` and `@JsonUnwrapped` is populated from attacker JSON even when a more restrictive view is active. ## Impact View-restricted unwrapped creator parameters can be set from untrusted input where `@JsonView` is used as a write-side authorization boundary. ## Affected / Patched (verified via `git tag --contains`) - 2.21 line: `>= 2.21.0, < 2.21.4` -> fixed in **2.21.4** (backport `721fa07`, #5973) - 3.x line: `>= 3.0.0, < 3.1.4` -> fixed in **3.1.4** (#5971, `d633bc0`) ## Severity / CWE Maintainer: minor. Reporter: HIGH. CWE-863 (Incorrect Authorization); related CWE-284. ## Credits Omkhar Arasaratnam (@omkhar) - finder.
