GHSA-GX83-3VF8-GH7J jackson-databind: Comparable missing from DefaultBaseTypeLimitingValidator's unsafe base types (incomplete PolymorphicTypeValidator denylist)

Summary DefaultBaseTypeLimitingValidator — the PolymorphicTypeValidator used automatically whenever @JsonTypeInfo is applied without an explicitly configured custom validator — denies polymorphic resolution only for nine specific "unsafe base types" Object, Serializable, Closeable, AutoCloseable,...

jackson-databind: Duration XMLGregorianCalendar Unbounded Number Parse DoS

Summary jackson-databind 3.2.1 deserializes a JSON string bound to a javax.xml.datatype.Duration or javax.xml.datatype.XMLGregorianCalendar field by passing the raw string verbatim to DatatypeFactory.newDurationvalue / newXMLGregorianCalendarvalue. Per the XML-Schema lexical grammar these factory...

Deserialization Of Untrusted Data

jackson-databind is vulnerable to Deserialization Of Untrusted Data. The vulnerability is due to insufficient restriction of attacker-controlled URI schemes when deserializing java.nio.file.Path, which allows an attacker to select and invoke a registered third-party FileSystemProvider and...

Server-Side Request Forgery (SSRF)

jackson-databind is vulnerable to Server-Side Request Forgery SSRF. The vulnerability is due to InetAddress.getByName resolving attacker-controlled input, which allows an attacker to trigger DNS requests from the server and probe or identify internal hosts...

Unsafe Polymorphic Deserialization

jackson-databind is vulnerable to unsafe polymorphic deserialization. The vulnerability is due to DefaultBaseTypeLimitingValidator allowing essentially any class implementing Comparable, which allows an attacker to provide a crafted type identifier and instantiate attacker-chosen objects such as...

Uncontrolled Resource Consumption

jackson-databind is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to the deserialization of arbitrarily long numeric components in XML datatype strings without length validation, which allows an unauthenticated attacker to submit specially crafted JSON values that caus...
