Severity:
External call recipient may consume all transaction gas
Summary
External call recipient may consume all transaction gas
Vulnerability Details
There is no limit specified on the amount of gas used, so the recipient can use up all of the transaction's gas, causing it to revert. Use addr.call{gas: <amount>}("") or this library instead
