Description

Wildcard permissions grant broad permissions. The best practice recommends providing only required permissions explicitly.

How to fix?

Ensure that the action attribute is not set to an invalid action.

Invalid actions are:

  • "*"
  • "lambda:*"

Example configuration:

resource "aws_lambda_permission" "example" {
  action = "lambda:InvokeFunction"
  # other required fields here
}
