Description

SQS queue policies must not grant Allow permissions to a wildcard principal (*) combined with wildcard actions, as this gives any principal unrestricted ability to send, receive, delete, or otherwise manipulate queue messages, risking data exposure, message loss, or unauthorized message injection. In Ansible tasks using the community.aws.sqs_queue or sqs_queue module, inspect the policy property for policy statements where Effect is "Allow", Principal is "*" (either Principal == "*" or Principal.AWS contains "*"), and Action contains "*". Such statements are flagged.

Define explicit principals (AWS account ARNs, IAM role/user ARNs, or service principals) and restrict Action to the minimal SQS actions required (for example, sqs:SendMessage, sqs:ReceiveMessage). You can optionally add conditions (source ARN/IP, VPC) to further limit access.

Secure configuration example:

- name: Create SQS queue with restricted policy
  community.aws.sqs_queue:
    name: my-queue
    policy:
      Version: "2012-10-17"
      Statement:
        - Sid: AllowSpecificAccount
          Effect: Allow
          Principal:
            AWS: "arn:aws:iam::123456789012:root"
          Action:
            - "sqs:SendMessage"
            - "sqs:ReceiveMessage"
          Resource: "arn:aws:sqs:us-east-1:123456789012:my-queue"

    receive_message_wait_time: 20
    policy:
      Version: '2012-10-17'
      Statement:
      - Effect: Allow
        Action: sqs:*
        Resource: '*'
        Principal: Principal
    make_default: false
    state: present
