Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The receipt validation mechanism failed to confirm that the verified block belonged to the canonical Ethereum chain, permitting attacks using orphaned block states to bypass verification gates.
Denial of Service: Unchecked arithmetic multiplication in inflation calculations and lock rate computations can trigger runtime panics, resulting in node crashes.
Denial of Service: Unbounded public key inputs in the BLS12-381 precompile can exhaust CPU resources because execution costs did not scale correctly with actual computational complexity.
