critical Security checks security Deserialization conf 1.00 3 occurrences [SEC101] Unsafe Java object deserialization (ObjectInputStream): Java ObjectInputStream deserializes untrusted bytes into objects. Attacker-controlled streams trigger gadget chains (Apache Commons Collections, etc.) leading to RCE.

Avoid native Java serialization entirely. Use JSON (Jackson with default-typing OFF) or a length-limited Protobuf. If you must, set up a SerialKiller / lookahead-deserializer with a class allowlist.

Duplicate implementation blocks are maintenance debt. Keep them visible, but they are not a high-severity defect unless the duplicated logic is security-sensitive or drifting.
