Oracle provider Pragma's September 18 assessment identified 6 out of 22 mainnet market and rate feeds as critical risk, warning that an available token price does not guarantee sufficient liquidity for lenders to sell collateral and cover loans. This assessment follows a September 17 borrowing exploit at Nostra, a lending protocol on Starknet, where a manipulated NSTR oracle price allowed an account to borrow approximately $3.5 million in other assets against NSTR collateral. Pragma rated BROTHER, DAI, DOG, EKUBO, LORDS, and NSTR as critical, with nine other feeds rated high risk.
