codeql/java-all 0.8.3 (changelog, source)

Module Jackson

Provides classes and predicates for working with the Jackson serialization framework.

Import path

import semmle.code.java.frameworks.Jackson

Imports

java	Provides all default Java QL imports.

Predicates

createJacksonJsonParserStep	Holds if `fromNode` to `toNode` is a dataflow step that creates a Jackson parser.
createJacksonTreeNodeStep	Holds if `fromNode` to `toNode` is a dataflow step that creates a Jackson `TreeNode`.
hasArgumentWithUnsafeJacksonAnnotation	Holds if `call` is a method call to a Jackson deserialization method such as `ObjectMapper.readValue(String, Class)`, and the target deserialized class has a field with a `JsonTypeInfo` annotation that enables polymorphic typing.

Classes

EnableJacksonDefaultTyping	A call that enables the default typing in `ObjectMapper`.
JacksonTypeDescriptorType	A type descriptor in Jackson libraries. For example, `java.lang.Class`.
MapperBuilder	A builder for building Jackson’s `JsonMapper`.
ObjectMapperReadMethod	A method in `ObjectMapper` that deserialize data.
ObjectMapperReadQualifier	A qualifier of a call to one of the methods in `ObjectMapper` that deserialize data.
SetPolymorphicTypeValidatorSource	A source that sets a type validator.
