Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The use of a shared singleton for transaction serialization in ExecutionService allowed distinct smart contracts running within the same process to share a single serializer instance, leading to cross-contract state leakage and transaction isolation bypass.
Auth Bypass: Failure to validate key boundaries allowed simple keys starting with the 0x00 delimiter to bypass composite key namespace separation, potentially exposing unauthorized state ranges via getStateByRange.
Information Disclosure: Unsanitized exception handling in ContractRuntimeException and ResponseUtils leaked verbose system error details and stack traces directly to external callers, facilitating reconnaissance.
