How to fix?

Upgrade github.com/evmos/evmos/v19/precompiles/testutil/contracts to version 19.0.0 or higher.

Overview

Affected versions of this package are vulnerable to Improper Authorization due to the misuse of the contract.CallerAddress authorization check in the code, which does not verify the source of the funds. An attacker can drain funds from any account on the chain by creating a vesting account funded by a third-party account without the third party's permission. This is only exploitable if the attacker can create a vesting account and an authorization for a contract.CallerAddress.
