Wu Says learned that Aave has released a new ChainSecurity security audit report for V4. The scope covers core contracts such as the Liquidity Hub, Spoke, and position managers. The report found no critical or high-severity issues; it identified 3 medium-severity and 9 low-severity issues, all of which have been addressed through code fixes or standardized adjustments, including issues where fee rounding could lead to a drop in share price, and small rounding errors could trigger liquidations and increase debt. This audit corresponds to v0.5.7, and at the time the report was completed, the subsequent v0.5.9 version was still under review.
