Vulnerability details
Uniswap v3 does not support rebasing or fee-on-transfer tokens so using these tokens with it will result funds getting stuck. With fee-on-transfer tokens, if the balance isn't checked, the wrong amount may be transferred out. With rebasing tokens, the contract may have some remaining residual balance after the fixed amount is transferred out. Uniswap v2 does support them but only with the "SupportingFeeOnTransfer" swap variants.
