Prior to versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1 on their respective release lines, the java.net.InetAddress branch of FromStringDeserializer.Std._deserialize() calls InetAddress.getByName() on attacker-controlled input, causing eager DNS resolution during deserialization and enabling DNS-based server-side request forgery and internal-host enumeration. This issue is fixed in versions 2.18.9, 2.21.5, 2.22.1, 3.1.5, and 3.2.1."
