HypurrFi reveals that early versions of Aave V3 had a rounding error vulnerability, and the addition of new lending markets for XAUT0 and UBTC has been suspended.

AAVE-3,88%

Gate News: On March 6, HyperEVM’s native non-custodial lending protocol HypurrFi disclosed on X that versions of Aave V3 prior to 3.5 contain a “rounding error” vulnerability. Under certain conditions, attackers can repeatedly execute supply/withdraw and borrow/repay cycles to extract underlying tokens. The affected markets are XAUT0 and UBTC within HypurrFi Pooled. HypurrFi stated that user funds are currently not at risk. To ensure safety, new supply and borrow operations in these markets have been suspended, while withdrawal and repayment functions remain operational. Other markets are functioning normally. HypurrFi added that the issue was quickly detected on-chain through internal monitoring systems, and affected markets have been frozen. They are collaborating with other Aave deployers and security researchers to address the problem and have invited other Aave fork projects to contact them for more security information.
