CVE-2026-54512

jackson-databind contains a PolymorphicTypeValidator (PTV) bypass vulnerability. When polymorphic typing is enabled and the type ID includes generic parameters, DatabindContext._resolveAndValidateGeneric() validates only the raw container class name, then parses the full canonical type without va...
