Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: The IPFS proxy and related webhook endpoints historically suffered from authorization bypasses due to missing authentication checks on routing branches and improper decoding of credentials. Enforcing robust authentication middleware across all API routing paths is essential to secure sensitive interfaces.
Logic Error: Mathematical comparisons in balance validation allowed users to initiate token transfers exceeding their available balance. Strict mathematical verification using arbitrary-precision arithmetic (BigNumber) is required for all balance and withdrawal calculations.
Auth Bypass: Identity smart contract components suffered from critical authorization bypasses allowing unauthorized key removals or replay/double-execution of authorized calls. Ensuring strict state checks and signature validation against known key purposes is critical.
