PANews, March 6 — HyperEVM’s native non-custodial lending protocol HypurrFi announced on X that versions of Aave V3 prior to 3.5 have 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. Currently, user funds are not at risk. To ensure safety, new supply and borrowing operations have been paused in the affected markets, 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, 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.
