Delegatecall

Description:

delegatecall is tricky to use and wrong usage or incorrect understanding can lead to devastating results.

You must keep 2 things in mind when using delegatecall

1. delegatecall preserves context (storage, caller, etc...)
2. storage layout must be the same for the contract calling delegatecall and the contract getting called

Remediation:

Use stateless Library
