Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Nested transaction architectures (such as Cosmos authz) can bypass module-specific message routing filters, allowing high-privileged actions like MsgEthereumTx to execute context-free.
Auth Bypass: Performing fee conversion operations after verifying the fee-grant allowance creates a logic loophole where unauthorized fee assets are deducted from a granter's account.
Denial of Service: EVM-to-Cosmos precompile bridging code is susceptible to node-crashing panics from unvalidated or nil parameters (such as lookback periods or denom string bounds).
