XRPL payment engine overflow could have minted XRP
XRPL disclosed a critical integer overflow in the XRP Ledger payment engine, present since the 2015 rewrite. Crafted offers plus one payment could have created spendable XRP beyond the 100 billion supply cap. Veria Labs says its AI found it; RippleX shipped xrpld 3.4.1 in three days. No mainnet exploitation found. No CVE.
