Miggo AIRoot Cause AnalysisThe vulnerability stems from improper synchronization when fetching chainId and accounts during connection initialization. The original implementation in multiple connectors used Promise.all() for parallel requests to eth_chainId and eth_accounts. This created a race condition where chainId could be resolved before potential chain changes triggered by user interaction during account authorization. The fix in PR #749 changed this to serial execution (accounts first then chainId), indicating the vulnerable pattern was present in the activation flows of EIP1193-derived connectors. High confidence comes from the explicit PR changes showing these functions were modified to address the synchronization issue.
