The ConcentratedLiquidityPoolManager keeps all tokens for all incentives in the same contract. The reclaimIncentive function does not reduce the incentive.rewardsUnclaimed field and thus one can reclaim tokens several times.
This allows anyone to steal all tokens from all incentives by creating an incentive themself, and once its expired, repeatedly claim the unclaimed rewards until the token balance is empty.
An attacker can steal all tokens in the PoolManager.
In reclaimIncentive, reduce incentive.rewardsUnclaimed by the withdrawn amount.
