jackson-databind: jackson-databind: Information disclosure and data manipulation via view-based access control bypass (CVE-2026-54518)

Overview

A flaw was found in jackson-databind. This vulnerability allows a remote attacker to bypass security view restrictions by sending specially crafted JSON (JavaScript Object Notation) data. The UnwrappedPropertyHandler component, which processes unwrapped properties, incorrectly populates constructor parameters that should be hidden by an active security view. This can lead to unauthorized information disclosure or data manipulation.
