Improperly Controlled Modification of Dynamically-Determined Object Attributes

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 Improperly Controlled Modification of Dynamically-Determined Object...

jackson-databind's renamed @JsonIgnore'd setters can deserialize via private fields

Summary POJOPropertiesCollector.renameProperties allows a property with @JsonProperty"renamed" on the getter and @JsonIgnore on the setter to be renamed rather than dropped. With MapperFeature.INFERPROPERTYMUTATORS enabled default, the private backing field is retained; during deserialization...

GHSA-5JMJ-H7XM-6Q6V jackson-databind has case-insensitive deserialization bypasses per-property @JsonIgnoreProperties

Summary In BeanDeserializerBase.createContextual, per-property @JsonIgnoreProperties exclusions are applied by handleByNameInclusion, producing a contextual deserializer whose BeanPropertyMap has the ignored properties removed. The subsequent per-property case-insensitivity block triggered by...

GHSA-RMJ7-2VXQ-3G9F jackson-databind has an array subtype allowlist bypass in BasicPolymorphicTypeValidator (allowIfSubTypeIsArray)

Summary BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray allowlists any array type based only on clazz.isArray, without validating the array's component element type against the configured allowlist. A PTV built with allowIfSubTypeIsArray plus an explicit concrete-type allowlist...

Incomplete List of Disallowed Inputs

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 Incomplete List of Disallowed Inputs in the...

Incomplete List of Disallowed Inputs

Overview Affected versions of this package are vulnerable to Incomplete List of Disallowed Inputs in the BasicPolymorphicTypeValidator.Builder.allowIfSubTypeIsArray method, which allowlists an array based only on clazz.isArray and does not validate the array's component type. An attacker who...

GHSA-J3RV-43J4-C7QM jackson-databind has a PolymorphicTypeValidator bypass via generic type parameters that allows arbitrary class instantiation

jackson-databind's PolymorphicTypeValidator PTV is the primary safety mechanism guarding polymorphic deserialization. When polymorphic typing is enabled and a type identifier contains generic parameters i.e. the type ID string contains when only java.util.ArrayList is allow-listed. The container...

Deserialization of Untrusted Data

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 Deserialization of Untrusted Data in the...

Deserialization of Untrusted Data

Overview Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the DatabindContext.resolveAndValidateGeneric method, which validates only the raw container class of a type identifier against the configured PolymorphicTypeValidator and not its nested generic type...

GHSA-3WRR-7QPF-2PRH jackson-databind: Deeply nested JsonNode throws StackOverflowError for toString()

Impact Potential Denial-of-Service when attacker sends deeply nested JSON if and only if service: 1. Reads deeply nested 1000s of levels JSON as JsonNode ObjectMapper.readTree 2. Writes out same or modifided node using JsonNode.toString which can consume significant amount of resources with...

GHSA-RCQC-6CW3-H962 jackson-databind has a @JsonView bypass for unwrapped creator parameters

Summary UnwrappedPropertyHandler.processUnwrappedCreatorProperties replays buffered JSON into creator parameters but never consults prop.visibleInViewactiveView. The normal property-based creator path gates creator properties on the active view, but this unwrapped-creator replay path bypasses tha...
