Security researchers at Veria Labs disclosed a payment-engine flaw that their proof of concept could use to create roughly 18.45 trillion XRP in a single transaction. That is about 184 times the 100 billion XRP created when the ledger launched.

The firm’s AI security agent first identified two issues that looked relatively modest on their own. Researchers then chained them together: one calculation could overflow while adding XRP amounts across offers, and a separate supply-protection counter could also wrap around.

Veria said an attacker could arrange 256 funded accounts and submit an
