CVE-2026-59889 Details
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.
A vulnerability in Jackson Databind allows for privilege escalation by bypassing JsonView guards on properties annotated with JsonUnwrapped. This issue affects versions 2.18.0 prior to 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1. The vulnerability arises because the UnwrappedPropertyHandler.processUnwrapped() method replays buffered JSON for JsonUnwrapped properties without checking if the property is visible in the active view. As a result, an attacker can manipulate JSON to overwrite properties under a less-privileged view, leading to unauthorized changes in application state.
Users can upgrade to Jackson Databind versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, or 3.2.1 to address this vulnerability.
