We recently discovered a critical bug in the token-lending contract of the solana-program-library (SPL). This blog post details our journey from discovery, through exploitation and coordinated disclosure, and finally the fix.
The total TVL at risk was about 2.600.000.000 USD. Some of that value is lent out, and some other low-value coins are not economically viable to steal, but the potential profit was easily in the hundreds of millions.
The bug was fixed, and dapps updated promptly to close the vulnerability. We believe the most secure code is open-source, and as auditors we believe one of the best ways to write better code is to understand vulnerabilities.
