Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Integer Overflow: Multiple overflow fixes in reward and redistribution math show a pattern of unchecked multiplication before division, which can corrupt token supply accounting.
Integer Overflow: Fee/reward share computation overflowed during multiplication, threatening delegator payouts. The fix reordered operations to compute percentage points first.
Authentication Bypass: Ticket replay was possible without validating creation round and block hash; the fix added these checks plus expiration, indicating a gap in ticket lifecycle validation.
