bug(aws): false positive on Hardcoded AWS Access Key In Lambda, (2564172f-c92b-4261-9acd-464aed511696)

[pepdekpd]

Running Kics github action 2.0 on lambda with following environment variables:

apiCredentials = <name of secure ssm parameter>
entity = <name>
logLevel = <loglevel>
progressMarker = <name of ssm parameter>
region = <region>
targetBucket = <bucketname>

Results in:

Hardcoded AWS Access Key In Lambda, Severity: HIGH, Results: 4
Description: Lambda access/secret keys should not be hardcoded
Platform: CloudFormation

		319:      "Variables": {
		320:       "progressMarker": {

Expected Behavior

I do no think this is an issue, the variables (apiCredentials, progressMarker) point to names of systems manager parameter store parameters. The lambda retrieves the credentials values using the names of the parameters, it is not "Hardcoded AWS Access Key In Lambda", so the vulnerability should not be raised in this case.

It's possible for you to provide more information regarding your problem? Our internal AppSec team was not able to reproduce the problem.

If you can provide us with a mock code sample with no sensitive information and also triggers the same problem as the original code sample, will help us a lot to fully understand the problem and provide you with the best information.
