Secrets Manager Secret Publicly Accessible

What this rule checks

Detects Secrets Manager secrets whose resource policy grants access to a wildcard or public principal.

How to fix it

1. 1Remove wildcard/public principals from the secret resource policy
2. 2Scope access to specific IAM principals or accounts

import { Secret } from 'aws-cdk-lib/aws-secretsmanager';
import { PolicyStatement, Effect, AnyPrincipal } from 'aws-cdk-lib/aws-iam';

const secret = new Secret(this, 'DbSecret');
secret.addToResourcePolicy(new PolicyStatement({
  effect: Effect.ALLOW,
  principals: [new AnyPrincipal()],
  actions: ['secretsmanager:GetSecretValue'],
  resources: ['*'],
}));

import { Secret } from 'aws-cdk-lib/aws-secretsmanager';
import { Role, ServicePrincipal } from 'aws-cdk-lib/aws-iam';

const role = new Role(this, 'AppServiceRole', { assumedBy: new ServicePrincipal('lambda.amazonaws.com') });
const secret = new Secret(this, 'DbSecret');
secret.grantRead(role);

Intentional? Suppress this finding

Sometimes a flag is deliberate — a genuinely public endpoint, say. You can dismiss secrets-manager-rotation-disabled and the reason is kept in the report, not silently hidden.

In .cdk-insights.json:

{
  "ignoreRules": [
    { "id": "secrets-manager-rotation-disabled", "reason": "Why this is intentional" }
  ]
}

Or inline in your CDK code:

Validations.of(scope).acknowledge({
  id: 'cdk-insights::secrets-manager-rotation-disabled',
  reason: 'Why this is intentional',
});

Use the rule ID secrets-manager-rotation-disabled shown above — not the CDK-* ID from SARIF / GitHub code scanning. To dismiss every finding on one construct instead, use ignorePaths. Suppression docs →
