A Decade-Old XRP Ledger Bug Could Have Minted XRP Out of Thin Air

The XRP Ledger quietly patched a 2015-era payment engine flaw that could have let an attacker create spendable XRP beyond the network’s fixed supply for just a few hundred XRP in reserves. The problem sat inside the code that settles payments across the XRP Ledger’s built-in decentralized exchange (DEX). According to the official vulnerability disclosure report published yesterday, when a single payment consumed many offers, the engine added up the amounts using unchecked 64-bit arithmetic. By pushing that sum high enough, it “wrapped around,” which is what an integer overflow does.
