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...
