According to The Block, the XRP Ledger team patched a long‑standing overflow issue in its payment engine. The vulnerability existed for more than ten years and would have permitted a single transaction to generate roughly 18 trillion spendable XRP if exploited.
The bug related to numeric overflow within the ledger’s calculation of outputs when processing payments. Under certain conditions, the ledger’s internal arithmetic could produce an artificially large amount without proper validation.
Developers identified the issue during routine code review and released a fix that corrects the overflow handling in the payment engine. The patch ensures that calculations stay within defined limits and prevents any unintended generation of excessive XRP amounts.
The correction does not affect existing ledger state or previously issued XRP. It only improves safety for future transaction processing. No public exploit of the bug has been reported, and the team emphasized that the fix addresses a theoretical risk rather than an active threat.
