XRP Ledger (BITSTAMP:XRPUSD) developers released a vulnerability disclosure detailing an emergency software update, xrpld 3.4.1, designed to patch a critical flaw in the network payment engine. Originally reported through a bug bounty program on September 22, 2026, the integer overflow bug had been present in the code since 2015 and could have allowed a malicious actor to create unauthorized XRP tokens in a single transaction.

The flaw stemmed from how the ledger processed complex payments involving multiple order book offers. When transaction totals exceeded the maximum integer limit, calculations wrapped around to a tiny sum, charging the sender a fraction of the actual cost while crediting recipients in full. Built-in system safety checks also wrapped identically, masking the error. Developers confirmed that no public network exploits were detected before the emergency release on September 25, 2026.

To deploy the fix immediately, developers bypassed the traditional amendment voting process for the first time in over ten years. Server operators are urged to update to xrpld 3.4.1 right away to keep their systems secure and synchronized with the broader network. XRP traded around 1.402 USD, up 0.52% on the day.
