MSCA-15
Missing Validation for Execution Function in SessionKeyPermissionsPlugin Hooks

For the second portion of the recommendation.

However, even if the function selector is validated in the pre-execution hook, the plugin still cannot ensure that the hook is not triggered by a random plugin via the executeFromPlugin() call. Checking whether the sender supports the IPlugin interface does not fully solve the
issue since the sender can manipulate the return values of the supportsInterface() call. A possible mitigation is to add a flag that indicates whether the call to the hook is triggered via executeFromPlugin() or not.

If a plugin is authorized to call executeWithSessionKey, therefore passes the validations and hook checks, then updating limit for the session key is fine. No fix needed here.
