NewCVE-2026-54518 (opens in a new tab)How to fix?
Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.21.4 or higher.
Overview
com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.
Affected versions of this package are vulnerable to Incorrect Authorization in the UnwrappedPropertyHandler.processUnwrappedCreatorProperties() method, which replays buffered JSON into creator parameters without consulting prop.visibleInView(activeView). An attacker can set view-restricted constructor parameters annotated with both @JsonView and @JsonUnwrapped, such as admin-only fields, from untrusted JSON by supplying them during deserialization while a more restrictive view is active, defeating the @JsonView write-side authorization boundary.
