On September 25, the 
XRP Ledger team disclosed and patched a critical overflow bug in its payment engine that could have compromised the cryptocurrency's supply cap. The vulnerability, if exploited, would have allowed an attacker to mint an unauthorized amount of XRP tokens.
According to The Block, the bug could have enabled the creation of approximately 18 trillion XRP in a single transaction. This is particularly significant given XRP's fixed supply cap of 100 billion tokens. The potential inflation would have drastically altered XRP's monetary policy and market dynamics.
Crypto Daily corroborates the existence of the bug and the September 25 patch date but does not provide the specific amount of potential inflation. The Block's report offers a more detailed technical analysis of the vulnerability's impact.
The XRP Ledger has faced previous scrutiny over its consensus mechanism and decentralization, but this incident underscores the importance of security in maintaining the integrity of a blockchain's economic model.
