CVE-2026-59889— jackson-databind: @JsonView ypassed for @JsonUnwrapped container properties on deserialization

Quick assessment

Affected
FasterXML jackson-databind
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

FasterXML jackson-databind是FasterXML组织开源的其中的一个具有数据绑定功能的组件。 FasterXML jackson-databind存在授权问题漏洞，该漏洞源于UnwrappedPropertyHandler.processUnwrapped()在回放缓冲JSON时缺少prop.visibleInView()检查，允许具有@JsonView和@JsonUnwrapped注解的属性在低权限活动视图下被写入。以下版本受到影响：2.18.0至2.18.9之前版本、2.21.

Vulnerability Title
jackson-databind: @JsonView ypassed for @JsonUnwrapped container properties on deserialization
Source: CVE Program / CVE List V5
Vulnerability Description
jackson-databind contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor. From 2.18.0 until 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1, UnwrappedPropertyHandler.processUnwrapped() replays buffered JSON for a @JsonUnwrapped property and calls prop.deserializeAndSet() without a prop.visibleInView(ctxt.getActiveView()) guard, allowing a property annotated with both @JsonView and @JsonUnwrapped to be written from attacker JSON under a less-privileged active view. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1.
