A decade-old flaw in the XRP Ledger has been fixed after researchers discovered a bug that could create unlimited spendable XRP.
A decade-old flaw in the XRP Ledger has been fixed after researchers discovered a bug that could create unlimited spendable XRP. XRP (XRP) is trading at $1.41. This is an original TLT brief synthesising 4 outlets (Crypto Adventure, Crypto Daily, The Block, and others), plus live market data, as of Mon, 12 Oct 2026 08:30:04 UTC.
The vulnerability posed a significant risk to XRP's supply cap and monetary policy, which are fundamental to its value proposition. If exploited, it could have undermined trust in the cryptocurrency's scarcity and security.
- XRP Ledger's payment engine contained a critical overflow vulnerability.
- The bug could have allowed minting 18 trillion XRP, exceeding supply cap.
- Researchers earned $250K bounty for responsible disclosure.
- XRP price up 1.29% despite bug disclosure.
Multiple outlets (Crypto Adventure, Crypto Daily, and Crypto.news) confirm that the XRP Ledger contained a critical vulnerability that could have allowed an attacker to create unlimited spendable XRP, bypassing its supply cap. They agree that the bug was reported through the XRPL Bug Bounty program and subsequently patched on September 25. However, Crypto.news specifies that the vulnerability could have minted up to 18 trillion XRP, a detail not mentioned by other outlets.

The 
XRP Ledger recently patched a critical vulnerability that could have allowed an attacker to create unlimited spendable XRP, according to multiple reports. The flaw was discovered in the payment engine and reported through the XRPL Bug Bounty program by researchers Cayden Liao and Veria AI on September 22.
The vulnerability, described as an overflow issue, could have enabled the creation of XRP beyond its intended supply cap. This posed a significant risk to the cryptocurrency's monetary policy and scarcity, which are foundational to its value proposition. RippleX engineers were able to reproduce the issue and deployed an emergency patch on September 25 to address the flaw.
The discovery and patching of the vulnerability were corroborated by Crypto Adventure, Crypto Daily, and Crypto.news. However, Crypto.news provided additional details, stating that the bug could have potentially minted up to 18 trillion XRP, a figure not mentioned by other outlets. This would have been a catastrophic event for XRP, given its current circulating supply of approximately 53 billion tokens.
The researchers who discovered the vulnerability were awarded a $250,000 bounty for their responsible disclosure, as reported by Crypto.news. This highlights the importance of bug bounty programs in maintaining the security and integrity of blockchain networks. The XRP Ledger has been in operation for over a decade, making the discovery of such a long-standing flaw particularly noteworthy.
In the broader market context, the total cryptocurrency market cap stands at $2.92 trillion, with 
Bitcoin up 1.24% over the past 24 hours. XRP itself is currently trading at $1.41, representing a 1.29% increase over the same period, despite the disclosure of the vulnerability. This suggests that investors may be reassured by the swift response in patching the flaw and the fact that no evidence of public exploitation has been found.
Since this brief published about 27 hours ago, XRP (XRP) has moved from $1.41 to $1.41 — +0.00%.

At today's peer-to-peer rate, 1 XRP ≈ ₦1,925.72 (about $1.41), up 1.1% over 24 hours. The naira itself trades about 2.7% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
