Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Logic Error: Inadequate verification of asset amounts allowed positive stablecoin minting during burn or liquidation operations. Attackers could exploit this to mint unauthorized tokens by bypassing expected negative value checks.
Auth Bypass: The lack of a Thread Token enforcement in the TokenSale state machine allowed unauthorized transition bypasses, enabling attackers to interact with counterfeit contract instances and manipulate state.
Logic Error: Missing input validation on prices and token amounts during state machine transitions allowed processing of negative or zero values, leading to unexpected financial states.
