Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Denial of Service: Unbounded request processing can cause memory exhaustion and node crashes. The GraphQL endpoint was vulnerable to DoS until maximum payload body limits and concurrency limit middleware were introduced. Developers must ensure all HTTP/GraphQL routes enforce strict resource limits.
Double Spending: Critical logical bypasses in transaction status evaluation could allow asset generation or double-spending. Specifically, transaction withdrawal messages were processed even when parent transactions reverted, which required checking the explicit transaction execution status to resolve.
Auth Bypass: Skipping essential signature checks during validation configurations can compromise the entire ledger's state. When UTXO validation was enabled, signature verification of transaction input signatures was mistakenly bypassed, leaving inputs unguarded.
