Security Audit Flags 11 Vulnerabilities in Aave V3, Rates Risk 7.4 out of 10

A security audit of Aave V3, the decentralized lending protocol with approximately $17.7 billion in total value locked, identified 11 vulnerabilities across reentrancy and access-control domains, with three rated Critical. The review, dated September 2026, found improperly guarded external calls in flash-loan and collateral-withdrawal paths, as well as overly broad admin role assignments in the upgrade proxy. Auditors warned that a successful reentrancy exploit on the flash-loan entry point could theoretically allow an attacker to drain up to $1.2 billion before liquidation mechanisms respond. None of the vulnerabilities are currently exploitable on the live mainnet, as existing safeguards such as reentrancy guards and multi-signature governance provide interim protection. However, the audit stresses that any future upgrade or misconfiguration removing those defenses could expose the protocol to significant risk, making prompt remediation essential.
