Impact:
Likelihood:
'collectFee()' Is Vulnerable to Denial via Failed WETH Transfer
Description: If the WETH transfer fails or is non-compliant, collectFee() reverts entirely, blocking ETH collection as well.
Impact: The collector could be permanently blocked from collecting fees due to one side failing.
Proof of Concept: If WETH transfer fails, this line halts execution:
i_weth.transfer(s_collector, collection);
Recommended Mitigation: Separate ETH and WETH collection into two safe functions. Add try-catch or fallback on failure.
