{"id":"GHSA-rcqc-6cw3-h962","summary":"jackson-databind has a @JsonView bypass for unwrapped creator parameters","details":"## Summary\n`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.\n\n## Impact\nView-restricted unwrapped creator parameters can be set from untrusted input where `@JsonView` is used as a write-side authorization boundary.\n\n## Affected / Patched (verified via `git tag --contains`)\n- 2.21 line: `\u003e= 2.21.0, \u003c 2.21.4` -\u003e fixed in **2.21.4** (backport `721fa07`, #5973)\n- 3.x line: `\u003e= 3.0.0, \u003c 3.1.4` -\u003e fixed in **3.1.4** (#5971, `d633bc0`)\n\n## Severity / CWE\nMaintainer: minor.
