Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Transaction sender recovery lacked chain ID validation, allowing acceptance of transactions from incorrect chains, effectively bypassing authentication of the transaction's origin network.
Crypto Validation: secp256k1 recovery did not validate that r is a valid x-coordinate on the curve, permitting invalid signatures to be accepted, enabling potential signature forgery or incorrect verification.
Consensus/Validation: Header validation was missing checks for difficulty, gas limit, timestamp, number, and extra data length, allowing invalid blocks to be accepted and enabling unauthorized state changes.
