@cozyfinance Loss: ~$160k
๐ Root Cause: The contract will automatically consider any undisputed YES = 1e18 price proposal submitted by any address via the UMA Optimistic Oracle as an external attack event. The trigger does not independently verify the authenticity of the Aave/Curve event; Cozy PToken's compensation eligibility is not tied to a snapshot of holdings prior to the event/UMA proposal.
An attacker-controlled executor submitted YES = 1e18 to two permissionless UMA Optimistic Oracle requests. The triggers accepted the affirmative proposals, and after settlement the markets transitioned to TRIGGERED, enabling CPT redemption.
