github.com/ethereum-optimism/op-geth is vulnerable to Always-Incorrect Control Flow Implementation

Medium Risk
This Affects:
github.com/ethereum-optimism/op-gethTL;DR
A flaw in the transaction pool handling of op-geth allows interop transactions to persist after a blockchain reorganization. Because these transactions may rely on state derived from an orphaned chain, they could be replayed or executed under inconsistent conditions on the new canonical chain. The issue is addressed by removing interop transactions from the txpool during reorg events.
