Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Bypassing transaction signature checks by invoking unvalidated extrinsic application APIs allows unauthorized transaction execution. Developers must always enforce strict signature verification paths over trusted ones.
Denial of Service: Unbounded pre-allocation of memory via user-supplied array lengths can cause out-of-memory panic states in critical EVM precompile execution paths, halting transaction validation.
Auth Bypass: Missing unique identifier tags in the transaction validation queue for unsigned transactions allows attackers to perform transaction replay attacks, bypassing transaction verification mechanisms.
