[Bug]: Regression in version 5.60, aws_security_group_rule does not detect removed/changed Security Group Rule

[tonimaki]

Terraform Core Version

1.9.5

AWS Provider Version

5.60, 5.68

Affected Resource(s)

• aws_security_group_rule

Expected Behavior

When a Security Group Rule is removed/changed in AWS Console, the terraform plan should detect that and suggest recreation/modification of the removed/changed rule.

Actual Behavior

Since version 5.60, when a Security Group Rule is removed/changed in AWS Console, the terraform plan does not suggest any changes

Terraform Configuration Files

provider "aws" {
  region = "us-east-1"
}

terraform {
  required_providers {
    aws = {
      source = "hashicorp/aws"
      #version = "5.59.0" # Still detects removed SG rule
      #version = "5.60.0" # Does not detect removed SG rule
      version = "5.68.0" # Does not detect removed SG rule
    }
  }
}

resource "aws_security_group" "test_sg" {
  name = "test_sg"
}

resource "aws_security_group_rule" "test_rule" {
  type              = "ingress"
  from_port         = 443
  to_port           = 443
  protocol          = "tcp"
  self              = true
  security_group_id = aws_security_group.test_sg.id
}

Steps to Reproduce

1. Create the security group and security group rule by terraform apply
2. Log into AWS Console and change the created rule from the created security group
3. Run terraform plan -> "No changes. Your infrastructure matches the configuration."
4. Remove the created rule from the created security group
5. Run terraform plan -> "No changes. Your infrastructure matches the configuration."
