Test your applicationsUpgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.9, 2.21.5 or higher.
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 deserializeUsingPropertyBasedWithExternalTypeId file. An attacker can populate restricted creator properties from untrusted input by crafting JSON that exploits the lack of view checks on parameters annotated with both @JsonView and @JsonTypeInfo(include=As.EXTERNAL_PROPERTY). This allows unauthorized assignment of sensitive fields, even when a restrictive view is active, by injecting values through polymorphic type information.
