Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Insecure Deserialization: Deserialized collections can bypass predicate checks designed to restrict element types or values if the predicate validation is not explicitly re-executed during the readObject lifecycle. This allows the construction of invalid or malicious collection states.

Deserialization Bug: Decorated lists that enforce uniqueness invariants are vulnerable to structural corruption during deserialization if duplicate elements or inconsistent structures are processed without validation in readObject.
