53 - Swapping on zero liquidity allows for control of the pool’s price

Swapping on a tick with zero liquidity enables a user to adjust the price of 1 wei of tokens in any direction.

As a result, an attacker could set an arbitrary price at the pool’s initialization or if the liquidity providers withdraw all of the liquidity for a short time.

Recommendation:

No straightforward way to prevent the issue. Ensure pools don’t end up in unexpected states. Warn users of potential risks.
