Sui Network Faces Multiple Outages Due to Upgrade Vulnerabilities

The Sui Network experienced three significant transaction halts over two days, attributed to vulnerabilities in its v1.72 upgrade. The first two outages were linked to flaws in the transaction fee deduction method, causing negative balances and crashes in validation nodes. The first interruption lasted six and a half hours, while subsequent outages occurred on Friday morning and afternoon. A temporary fix implemented on Thursday carried known risks, leading to further disruptions. The third outage was caused by an undisclosed vulnerability during a validator node restart. The Sui Foundation confirmed that user funds were never at risk and that both vulnerabilities have been resolved. A mechanism to forcibly terminate stalled epochs has been established to prevent future issues. AI agents were utilized to expedite the diagnostic process.

Key Points: • Sui Network experienced three outages due to vulnerabilities in its v1.72 upgrade. • The first two outages were caused by flaws in the transaction fee deduction method. • User funds were never at risk, and both vulnerabilities have since been fixed.
