XRP Ledger Fixes Decade-Old XRP Counterfeiting Bug

| decrypt.co
The XRP Ledger patched a critical payment-engine vulnerability that could have allowed attackers to create counterfeit XRP. Reported through the XRPL bug bounty program in September, the integer overflow had been present since 2015. Hundreds of specially crafted order-book offers could have made a buyer pay very little while sellers received full payment, creating spendable XRP. The ledger’s supply-check mechanism shared the arithmetic flaw, potentially allowing the counterfeit tokens to evade detection despite XRP’s 100 billion supply cap. Maintainers said there is no evidence the vulnerability was exploited on a public network. The fix shipped in xrpld 3.4.1 on 25 September, and more than 80% of validators on the default UNL had upgraded that day. Developers made the fix effective immediately upon upgrade, bypassing the usual amendment process to avoid leaving the XRP Ledger exposed after the patch became public. A separate validation issue involving the Batch feature was also disclosed; its activation was delayed until a fix was ready, and it had not gone live on mainnet. The XRP Ledger vulnerability has been fixed, and no counterfeit XRP or affected funds have been reported. The incident may prompt traders to scrutinize the network’s security and governance, but the swift patch and lack of known exploitation limit the immediate threat to XRP. Operators were advised to upgrade to version 3.4.1 or later. The article reported XRP at $1.38 on Monday, down 1.6% in 24 hours and 9.4% over seven days.
Neutral
The direct price impact on XRP is best assessed as neutral. The vulnerability was serious because it could have enabled the creation of spendable counterfeit XRP, threatening confidence in the ledger’s integrity. However, maintainers reported no evidence of exploitation, released a patch, and said most trusted validators had upgraded promptly. Those factors reduce the immediate risk of supply dilution or disruption to XRP trading. In the short term, the disclosure could still encourage caution or brief selling as traders assess the security and governance implications. The reported weekly decline may add to sensitivity, but the available information does not establish that the bug caused the price move. Over the longer term, confidence will depend on continued validator upgrades, transparent security reviews, and evidence that the fix works as intended. A successful response could contain lasting damage, while further vulnerabilities or signs of exploitation could renew downward pressure. With no known losses or counterfeit XRP and the fix already deployed, the news alone does not provide a clear directional catalyst.
