CVE-2026-54518

ADVISORY - github

Summary

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.
