Cloud Credential Provider Misuse

default-credential-chain-mismatch

Default SDK credential chains fail because runtime identity differs (e.g., not on EC2, missing creds.json in Docker), so auth lookup falls back to instance metadata and breaks, preventing assumed-role and service-account workflows from acquiring usable temporary credentials.

I do have `credentials: include` in all of my requests — on vercel. Tension: the cookies were not persistent. Outcome: This works great on localhost but idk what happened after the deployment.

MATCHESSolution

Implement role-based authorization as a reusable dependency (e.g., a callable class used with Depends) that loads the current user from the token and raises HTTP 403 when the user's role is not in the allowed roles; apply the dependency to routes.

MATCHESSolution

Double check the Cognito client's data against the data in AWS

MATCHESSolution

The issue was with keychain access. — the macos job keeps on hanging. Tension: I also had some trouble getting code signing and notarization to work. Outcome: creating a temporary one and unlocking it.

MATCHESSolution

It seems you need to configure AWS credentials instead of this action `chrislennon/action-aws-cli@v1.1` — The Github action that we have is failing with following error. Outcome: - name: Configure AWS credentials uses: aws-actions/configure-aws-credentials@v1.

MATCHESSolution

finally I could call firebase api via workflow identity by this code. — When using credentials obtained with Workload Identity. Tension: you cannot use it as an access token to call the Google Cloud API. Outcome: you need to get another access token.

MATCHESSolution

Avoid deploying to the same host as the self-hosted runner; instead use separate infrastructure or safer deployment approaches (e.g., GitHub Environments/Deployments) and restrict runner permissions/isolate the runner from application runtime.

MATCHESSolution

Solved by using this version of SDK — The imported function updateUserGroupStripe lives in a server-side module and interacts with AWS Cognito using the AWS SDK v3. Tension: Cannot destructure property 'environmentVariableSelector' of 'undefined' as it is undefined. Outcome: "@aws-sdk/client-cognito-identity-provider": "https://github.com/aws/aws-sdk-js-v3/issues/7051.

MATCHESSolution

I created a new Credential Provider that extends the AWS SDKs credential provider — internally binds to a RestClient which calls the roles anywhere `/sessions` endpoint. Tension: This action is configurable based on a simple boolean flag. Outcome: The code refreshes the AWS credentials just before expiry of the previous set of credentials.

MATCHESSolution

Try chaining with a WebIdentityTokenCredentialsProvider.

MATCHESSolution

Have you tried using the v4 token signing process on Cloud CDN? — No need to expose your S3 bucket publicly. Tension: Cloud CDN will be sending the "published hostname" towards the origin destination. Outcome: This will generate an emphemal access token to access a private AWS S3 bucket using your AWS IAM credentials.

MATCHESSolution

Create a helper to get the assumed role credentials — Using `CredentialProvider::memoize` cache's the credentials so if you need them elsewhere in your app. Tension: your app doesn't have to get new credentials every time. Outcome: Remember to register this Service Provider in your `app.php` config.

MATCHESSolution

Use the AWS SDK to call AssumeRole, then pass the returned temporary credentials to S3Client

MATCHESSolution

Set the desired profile as the default by updating AWS CLI configuration (e.g., set `AWS_PROFILE=profile_name` or configure the CLI default profile), or ensure the default credential source matches the profile that has access (valid environment/session credentials or correctly configured default profile).

MATCHESSolution

Use sessionClaims in clerkMiddleware() and customize the session token in the Clerk Dashboard to include org_name and org_role

MATCHESSolution

Your Azure AD Connect service should be using a dedicated service account. Tension: This allows them to detect new and unreported/unkown threats because they look for risky/unusual actions rather than simply a "bad" program. Outcome: allow this specific module import from a trusted user or host.

MATCHESSolution

Delete the default keychain on the CI machine and replace it with a user-created login.keychain

MATCHESSolution

swapping to `allowCredentials[0].rawId` would probably fix the issue — If it is not a `PublicKeyCredential`. Tension: the `id` is a `base64url` encoded string of the ID and not an actual `BufferSource`. Outcome: something like `new Uint8Array(Buffer.from(allowCredentials[0].id, 'base64'))` might solve it.

MATCHESSolution

Perform the authorization-code-to-token exchange in the backend to keep tokens and the client secret off the client. Create/establish an app-specific user session (e.g., HTTP session cookies or tokens) and do not use the external provider access token directly for your backend authorization; generate/validate authorization specific to your APIs.

MATCHESSolution

Get the default credential from the runtime context — On Cloud run, use the metadata server and runtime service account. Tension: When building a Docker image, the creds.json file isn't included, leading to failures in authentication.

MATCHESSolution

On your local machine, use your own credential directly — On your local machine, use your own credential directly. Tension: If you use your container locally, you can read my article to use your own credential in the local container runtime context.

MATCHESSolution

Or the same service account as Cloud Run use by impersonating it with your own credential — Or the same service account as Cloud Run use by impersonating it with your own credential.

MATCHESSolution

Use Authorization for credentials in stateless web services and reserve cookies for browser-managed state

MATCHESSolution

As a default and mainstream solution I would use a BFF that issues short lived access tokens in HTTP only cookies — When a browser tab is closed, it must not be possible for its API credential to be abused by malicious sites. Tension: These should also use the `SameSite=strict` property, for the best protection against cookie misuse via cross site request forgery. Outcome: These should also use the `SameSite=strict` property.

MATCHESSolution

Use Google OAuth to authorize the client in the browser — The client then uses the HTTP `Authorization: Bearer IDENTITY_TOKEN` header to make requests to Cloud Run. Tension: How to solve the problem of the security of the JSON file. Outcome: The client then uses the HTTP `Authorization: Bearer IDENTITY_TOKEN` header to make requests to Cloud Run.

MATCHESSolution

You need to create Identity Tokens for Cloud Run authorization — For either option. Tension: A frontend written in react and hosted on firebase hosting and a backend written in python/FastAPI on cloud run. Outcome: You need to create Identity Tokens for Cloud Run authorization for either option.

MATCHESSolution

I have used AzureCliCredential for authenticating with my Azure account. — Transparent Data Encryption with CMK was enabled in Azure SQL from Key vault successfully. Tension: Make sure your server_key_name is in this format. Outcome: Make sure your server_key_name is in this format -`KeyVaultName_KeyVaultKeyName_KeyVaultKeyVersion`.

MATCHESSolution

another solution that is to implement a service that query data from workspace-service and use it to validate — I want to implement authorization logic that check if a user has access to a particular cloud instance. Tension: the drawback of this solution. Outcome: I would use 2nd solution with longer token lifespan to not generate it so often.

MATCHESSolution

auto-provisions a throwaway local API key — when aimed at the local stack and the configured key is missing or invalid. Tension: the configured key is missing or invalid. Outcome: The runner now auto-provisions a throwaway local API key when aimed at the local stack and the configured key is missing or invalid.

MATCHESSolution

Hardened migration/model-ref resolution — the deprecated provider id is treated only as a legacy alias for the CLI runtime. Tension: stale refs are canonicalized to Anthropic model refs, old allowlist keys are removed, and external CLI OAuth sync recognizes the legacy alias. Outcome: external CLI OAuth sync recognizes the legacy alias.
