From 468d7117d1dfd08e7bfa6c299b561c5797aad7e9 Mon Sep 17 00:00:00 2001 From: Pahud Hsieh Date: Mon, 22 Sep 2025 21:33:04 -0400 Subject: [PATCH 01/20] fix(aws-dynamodb): addToResourcePolicy method now properly synthesizes to CloudFormation The addToResourcePolicy() method on DynamoDB Table constructs had no effect - resource policies added after table construction were not appearing in the synthesized CloudFormation template. This created a security gap where developers thought they were securing tables but policies weren't actually applied. Changes: - Initialize this.resourcePolicy from props in Table constructor - Use Lazy.any() for CfnTable resourcePolicy property to defer evaluation until synthesis - Follow the same pattern used by Global Secondary Indexes for consistency - Add comprehensive unit and integration tests This fix enables proper IAM policy scoping using table.tableArn instead of forcing users to use insecure "*" resource workarounds.

Using `table.tableArn` would create a circular dependency since the table references its own resource policy. Following the KMS pattern, use wildcards (`'*'`) or manually constructed ARNs to avoid this issue. + TableV2 doesn’t support creating a replica and adding a resource-based policy to that replica in the same stack update in Regions other than the Region where you deploy the stack update. To incorporate a resource-based policy into a replica, you'll need to initially deploy the replica without the policy, followed by a subsequent update to include the desired policy. diff --git a/packages/aws-cdk-lib/aws-dynamodb/lib/shared.ts b/packages/aws-cdk-lib/aws-dynamodb/lib/shared.ts index 22e45cb6c9d02..4eaf184e31f42 100644 --- a/packages/aws-cdk-lib/aws-dynamodb/lib/shared.ts +++ b/packages/aws-cdk-lib/aws-dynamodb/lib/shared.ts @@ -360,12 +360,6 @@ export interface ITable extends IResource { */ readonly tableStreamArn?: string; - /** - * The ARN to use in policy resource statements for this table. - * This ARN includes CloudFormation intrinsic functions for region and account ID. - */ - readonly policyResourceArn: string; - /** * * Optional KMS encryption key associated with this table. diff --git a/packages/aws-cdk-lib/aws-dynamodb/lib/table-v2-base.ts b/packages/aws-cdk-lib/aws-dynamodb/lib/table-v2-base.ts index f705e23d1647a..60ba7f6993a7d 100644 --- a/packages/aws-cdk-lib/aws-dynamodb/lib/table-v2-base.ts +++ b/packages/aws-cdk-lib/aws-dynamodb/lib/table-v2-base.ts @@ -56,15 +56,15 @@ export abstract class TableBaseV2 extends Resource implements ITableV2, IResourc public abstract readonly encryptionKey?: IKey; /** - * The ARN to use in policy resource statements for this table. - * This ARN includes CloudFormation intrinsic functions for region and account ID. + * The resource policy for the table */ - public abstract readonly policyResourceArn: string; + public abstract resourcePolicy?: PolicyDocument; /** - * The resource policy for the table + * The ARN to use in policy resource statements for this table. + * This ARN includes CloudFormation intrinsic functions for region and account ID. */ - public abstract resourcePolicy?: PolicyDocument; + protected abstract get policyResourceArn(): string; protected abstract readonly region: string; @@ -470,15 +470,16 @@ export abstract class TableBaseV2 extends Resource implements ITableV2, IResourc } /** - * Adds a statement to the resource policy associated with this file system. + * Adds a statement to the resource policy associated with this table. * A resource policy will be automatically created upon the first call to `addToResourcePolicy`. * - * Note that this does not work with imported file systems. + * Note that this does not work with imported tables. * * @param statement The policy statement to add */ public addToResourcePolicy(statement: PolicyStatement): AddToResourcePolicyResult { this.resourcePolicy = this.resourcePolicy ??

Following the same pattern as KMS, resource policies use wildcard resources to avoid circular dependencies: ```ts const table = new dynamodb.TableV2(this, 'Table', { partitionKey: { name: 'pk', type: dynamodb.AttributeType.STRING }, }); -// Basic resource policy with proper ARN construction -const cfnTable = table.node.defaultChild as dynamodb.CfnTable; -const tableLogicalId = cfnTable.logicalId; - +// Standard resource policy (recommended approach) table.addToResourcePolicy(new iam.PolicyStatement({ - actions: ['dynamodb:GetItem', 'dynamodb:PutItem'], + actions: ['dynamodb:GetItem', 'dynamodb:PutItem', 'dynamodb:Query'], principals: [new iam.AccountRootPrincipal()], - resources: [`arn:aws:dynamodb:\${AWS::Region}:\${AWS::AccountId}:table/\${${tableLogicalId}}`], + resources: ['*'], // Wildcard avoids circular dependency - same pattern as KMS })); -// Scoped resource policy (for advanced use cases) +// Allow specific service access table.addToResourcePolicy(new iam.PolicyStatement({ actions: ['dynamodb:Query'], principals: [new iam.ServicePrincipal('lambda.amazonaws.com')], + resources: ['*'], +})); +``` + +#### Scoped Resource Policies (Advanced) + +For scoped resource policies that reference specific table ARNs, you must specify an explicit table name: + +```ts +import { Fn } from 'aws-cdk-lib'; + +// Table with explicit name enables scoped resource policies +const table = new dynamodb.TableV2(this, 'Table', { + tableName: 'my-explicit-table-name', // Required for scoped resources + partitionKey: { name: 'pk', type: dynamodb.AttributeType.STRING }, +}); + +// Now you can use scoped resources +table.addToResourcePolicy(new iam.PolicyStatement({ + actions: ['dynamodb:GetItem'], + principals: [new iam.AccountRootPrincipal()], resources: [ - "arn:aws:dynamodb:us-east-1:123456789012:table/MusicCollection", - "arn:aws:dynamodb:us-east-1:123456789012:table/MusicCollection/index/GSI1", // Scoped to specific Global Secondary Index + Fn.sub('arn:aws:dynamodb:${AWS::Region}:${AWS::AccountId}:table/my-explicit-table-name'), + Fn.sub('arn:aws:dynamodb:${AWS::Region}:${AWS::AccountId}:table/my-explicit-table-name/index/*'), ], })); ``` -**Important:** Resources must be explicitly specified in the policy statement. Using `table.tableArn` would create a circular dependency since the table references its own resource policy. Following the KMS pattern, use wildcards (`'*'`) or manually constructed ARNs to avoid this issue. +**Important Limitations:** +- **Auto-generated table names**: Must use `resources: ['*']` to avoid circular dependencies +- **Explicit table names**: Enable scoped resources but lose CDK's automatic naming benefits +- **CloudFormation constraint**: Resource policies cannot reference the resource they're attached to during creation TableV2 doesn’t support creating a replica and adding a resource-based policy to that replica in the same stack update in Regions other than the Region where you deploy the stack update. To incorporate a resource-based policy into a replica, you'll need to initially deploy the replica without the policy, followed by a subsequent update to include the desired policy. diff --git a/packages/aws-cdk-lib/aws-dynamodb/test/dynamodb.test.ts b/packages/aws-cdk-lib/aws-dynamodb/test/dynamodb.test.ts index 7557dbec808ff..3c6f596e6607d 100644 --- a/packages/aws-cdk-lib/aws-dynamodb/test/dynamodb.test.ts +++ b/packages/aws-cdk-lib/aws-dynamodb/test/dynamodb.test.ts @@ -7,7 +7,7 @@ import * as iam from '../../aws-iam';
