🐛 Use `401` status code in security classes when credentials are missing #13786

This description is partially outdated after changes described in this comment.

Description

This PR is an attempt to finally solve the issue with security tools returning error responses with status code 403 instead of 401 when credentials are not provided.

Breaking changes and workaround

These changes can break projects that rely on old behavior.
In order to mitigate this, the not_authenticated_status_code is introduced. If set to 403, it will make it work the same way as it was before changes (return 403 status code).
This option should be treated as a temporary workaround to give developers more time to update Clients to follow the new behavior.

Changes and reasoning

APIKeyQuery, APIKeyHeader, APIKeyCookie

Standard:
- These schemes are not covered by standards, but developers usually follow the same rules as for other standards
Actions:
- The default status code for not providing API key was changed from 403 to 401.
- Temporary not_authenticated_status_code parameter can be used to revert this behavior back to returning 403 error code without sending WWW-Authenticate.
Notes:
- It’s considered to be a good practice to include in WWW-Authenticate information needed to understand how the key is supposed to be passed. I implemented default format (WWW-Authenticate: ApiKey in="...", name="..." ), but it’s possible to override the template for WWW-Authenticate by subclassing and defining the format_www_authenticate_header_value method

HTTP Basic

Standard:
- https://datatracker.ietf.org/doc/html/rfc7617
Actions:
- No needed. This scheme already acts according to the standard in terms of returning 401 status code with WWW-Authenticate header on a lack of credentials
Notes:
- realm is required according to the RFC, but optional in the current implementation. Fixing this would introduce breaking changes. Considering this is not a problem for people who want to follow the standard, I suggest we leave it as it is.

HTTP Digest

Standard:
- https://datatracker.ietf.org/doc/html/rfc7616
Actions:
- The default status code for not providing the authorization parameter was changed from 403 to 401.
- WWW-Authenticate is just a stub for now (just WWW-Authenticate: Digest) (see notes)
- Temporary not_authenticated_status_code parameter can be used to revert this behavior back to returning 403 error code without sending WWW-Authenticate.
Notes:
- Since the current HTTPDigest implementation is just a stub, we can’t follow standards (we don’t generate nonce's, don’t have realm, …). I suggest we just change the error status code and add a stub for WWW-Authenticate (just WWW-Authenticate: Digest). For now HTTPDigest can’t be used as it is, so, this is not a problem.
- We can later add full implementation of Digest scheme. There have been made several attempts to implement it (Update HTTPDigest to match RFC 7616 #9825, 🔒 Match HTTP Digest specs from RFC 7616 #3071)
- Should we add a note that HTTPDigest is just a stub?

HTTP Bearer, OAuth2 schemes, OIDC

Standard:
- https://datatracker.ietf.org/doc/html/rfc6750
Actions:
- For OAuth2PasswordBearer and OAuth2AuthorizationCodeBearer: not needed.
  - They already return a 401 error code. Implementation is probably not 100% correct (see notes), but considering nobody argued, I think we can leave it as it is for now.
- For HTTPBearer and OpenIdConnect:
  - The default status code for not providing the authorization parameter was changed from 403 to 401. The suggested implementation will be in line with the current implementations of OAuth2PasswordBearer and OAuth2AuthorizationCodeBearer.
  - Temporary not_authenticated_status_code parameter added to HTTPBearer can be used to revert this behavior back to returning 403 error code without sending WWW-Authenticate.
Notes:
- It’s recommended to return 400 error response if the parameter is missed or of an unsupported type, but this is not a strict requirement (word SHOULD is used). I suggest we ignore this and follow the approach that is consistent with other schemes.
- The format of WWW-Authenticate is not clearly described: It’s said that the value "Bearer" MUST be followed by one or more auth-param values. At the same time, all auth-param attributes are optional. In examples they always add realm. Since we don’t have realm, I suggest we just skip it and send just WWW-Authenticate: Bearer
- We can later improve the WWW-Authenticate format by adding realm and scope

Thank you for opening this @YuriiMotov - we've just been surprised by an API reporting 403 for a missing token when we we'd be expecting to see 401 and trigger a login flow on the client side.

We'd be glad to have this this fix merged. 🙏

(fwiw, I agree with the decision to follow other implementations and return 401 not 400)

Any progress?

Cito · 2025-08-06T11:52:40Z

We have been also noticing this and are waiting for a fix for a long time.

I ran into this too when using schemathesis testing a route protected by HTTPBearer

  | schemathesis.core.failures.FailureGroup: Schemathesis found 2 distinct failures
  | 
  | - Missing header not rejected
  | 
  |     Missing header not rejected (got 403, expected 401)

The if self.not_authenticated_status_code == HTTP_403_FORBIDDEN: checks look a bit clunky, but given this is of a temporary nature it is probably fine

Awesome, thank you @YuriiMotov! 🙌

And thank you for all the investigation and notes with all the research. 🤓 ☕

I made the following updates:

Simplify the WWW-Authenticate challenge for API key, as this is a custom challenge we are defining, I didn't want to also define custom parameters, but leave the simplest form.
Refactor the implementation to not have an extra parameter for defining the status code, instead, put the creation of the error in a method of the class, this way if someone wants to use the old behavior, they can create a subclass and override only that method.
Refactor the HTTP classes to all return the same message for errors ("Not authenticated"), instead of some times returning "Invalid authentication credentials", this simplifies the code a bit, and in particular makes it simpler to explain to users how to use the old behavior.
Simplify and refactor a bit the implementation.
Add new docs for how to use the old behavior by subclassing, with new source examples and tests for them.
Add notes and warnings about stub classes, as you suggested.

I also noted that the spec says that the realm is now optional, but only in a footer note (https://datatracker.ietf.org/doc/html/rfc7235#appendix-A). 😂 Anyway, we are good with that now.

This will be available in FastAPI 0.122.0, released in the next few hours. 🎉

[`v5.6.0`](https://github.com/celery/celery/blob/HEAD/Changelog.rst#560) [Compare Source](https://github.com/celery/celery/compare/v5.5.3...v5.6.0) \===== :release-date: 2025-11-30 :release-by: Tomer Nosrati Celery v5.6.0 is now available. Key Highlights ``` See :ref:`whatsnew-5.6` for a complete overview or read the main highlights below. Python 3.9 Minimum Version -------------------------- Celery 5.6.0 drops support for Python 3.8 (EOL). The minimum required Python version is now 3.9. Users still on Python 3.8 must upgrade their Python version before upgrading to Celery 5.6.0. Additionally, this release includes initial support for Python 3.14. SQS: Reverted to ``pycurl`` from ``urllib3`` -------------------------------------------- The switch from ``pycurl`` to ``urllib3`` for the SQS transport (introduced in Celery 5.5.0 via Kombu) has been reverted due to critical issues affecting SQS users: - Processing throughput dropped from ~100 tasks/sec to ~3/sec in some environments - ``UnknownOperationException`` errors causing container crash loops - Silent message processing failures with no error logs Users of the SQS transport must ensure ``pycurl`` is installed. If you removed ``pycurl`` after upgrading to Celery 5.5.0, you will need to reinstall it. Contributed by `@auvipy <https://github.com/auvipy>`_ in `#9620 <https://github.com/celery/celery/pull/9620>`_. Security Fix: Broker Credential Leak Prevention ------------------------------------------------ Fixed a security issue where broker URLs containing passwords were being logged in plaintext by the delayed delivery mechanism. Broker credentials are now properly sanitized in all log output. Contributed by `@giancarloromeo <https://github.com/giancarloromeo>`_ in `#9997 <https://github.com/celery/celery/pull/9997>`_. Memory Leak Fixes ----------------- Two significant memory leaks have been fixed in this release: **Exception Handling Memory Leak**: Fixed a critical memory leak in task exception handling that was particularly severe on Python 3.11+ due to enhanced traceback data. The fix properly breaks reference cycles in tracebacks to allow garbage collection. Contributed by `@jaiganeshs21 <https://github.com/jaiganeshs21>`_ in `#9799 <https://github.com/celery/celery/pull/9799>`_. **Pending Result Memory Leak**: Fixed a memory leak where ``AsyncResult`` subscriptions were not being cleaned up when results were forgotten. Contributed by `@tsoos99dev <https://github.com/tsoos99dev>`_ in `#9806 <https://github.com/celery/celery/pull/9806>`_. ETA Task Memory Limit --------------------- New configuration option :setting:`worker_eta_task_limit` to prevent out-of-memory crashes when workers fetch large numbers of ETA or countdown tasks. Previously, workers could exhaust available memory when the broker contained many scheduled tasks. Example usage: .. code-block:: python app.conf.worker_eta_task_limit = 1000 Contributed by `@sashu2310 <https://github.com/sashu2310>`_ in `#9853 <https://github.com/celery/celery/pull/9853>`_. Queue Type Selection for Auto-created Queues -------------------------------------------- New configuration options allow specifying the queue type and exchange type when Celery auto-creates missing queues. This is particularly useful for RabbitMQ users who want to use quorum queues with auto-created queues. Configuration options: - :setting:`task_create_missing_queue_type`: Sets the queue type for auto-created queues (e.g., ``quorum``, ``classic``) - :setting:`task_create_missing_queue_exchange_type`: Sets the exchange type for auto-created queues Example usage: .. code-block:: python app.conf.task_create_missing_queue_type = 'quorum' Contributed by `@ghirailghiro <https://github.com/ghirailghiro>`_ in `#9815 <https://github.com/celery/celery/pull/9815>`_.

I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc). This new version `0.120.0` only contains that transition to the new home package for that utility class `Doc`. ##### Translations - 🌐 Sync German docs.

And with this, support for **Pydantic v1 is now deprecated** and will be **removed** from FastAPI in a future version soon. **Note**: have in mind that the Pydantic team already stopped supporting Pydantic v1 for recent versions of Python, starting with Python 3.14. You can read in the docs more about how to [Migrate from Pydantic v1 to Pydantic v2](https://fastapi.tiangolo.com/how-to/migrate-from-pydantic-v1-to-pydantic-v2/). ##### Features - ✨ Add support for `from pydantic.v1 import BaseModel`, mixed Pydantic v1 and v2 models in the same app. MR [#14168](https://github.com/fastapi/fastapi/pull/14168) by [@tiangolo](https://github.com/tiangolo). ### [`v0.118.3`](https://github.com/fastapi/fastapi/releases/tag/0.118.3) [Compare Source](https://github.com/fastapi/fastapi/compare/0.118.2...0.118.3) ##### Upgrades - ⬆️ Add support for Python 3.14.

MR [#14099](https://github.com/fastapi/fastapi/pull/14099) by [@tiangolo](https://github.com/tiangolo). Before FastAPI 0.118.0, if you used a dependency with `yield`, it would run the exit code after the *path operation function* returned but right before sending the response. This change also meant that if you returned a `StreamingResponse`, the exit code of the dependency with `yield` would have been already run. For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not be able to use that session while streaming data because the session would have already been closed in the exit code after `yield`. This behavior was reverted in 0.118.0, to make the exit code after `yield` be executed after the response is sent. You can read more about it in the docs for [Advanced Dependencies - Dependencies with `yield`, `HTTPException`, `except` and Background Tasks](https://fastapi.tiangolo.com/advanced/advanced-dependencies#dependencies-with-yield-httpexception-except-and-background-tasks). Including what you could do if you wanted to close a database session earlier, before returning the response to the client. ##### Docs - 📝 Update `tutorial/security/oauth2-jwt/` to use `pwdlib` with Argon2 instead of `passlib`.

[`v5.6.0`](https://github.com/celery/celery/blob/HEAD/Changelog.rst#560) [Compare Source](https://github.com/celery/celery/compare/v5.5.3...v5.6.0) \===== :release-date: 2025-11-30 :release-by: Tomer Nosrati Celery v5.6.0 is now available. Key Highlights ``` See :ref:`whatsnew-5.6` for a complete overview or read the main highlights below. Python 3.9 Minimum Version -------------------------- Celery 5.6.0 drops support for Python 3.8 (EOL). The minimum required Python version is now 3.9. Users still on Python 3.8 must upgrade their Python version before upgrading to Celery 5.6.0. Additionally, this release includes initial support for Python 3.14. SQS: Reverted to ``pycurl`` from ``urllib3`` -------------------------------------------- The switch from ``pycurl`` to ``urllib3`` for the SQS transport (introduced in Celery 5.5.0 via Kombu) has been reverted due to critical issues affecting SQS users: - Processing throughput dropped from ~100 tasks/sec to ~3/sec in some environments - ``UnknownOperationException`` errors causing container crash loops - Silent message processing failures with no error logs Users of the SQS transport must ensure ``pycurl`` is installed. If you removed ``pycurl`` after upgrading to Celery 5.5.0, you will need to reinstall it. Contributed by `@auvipy <https://github.com/auvipy>`_ in `#9620 <https://github.com/celery/celery/pull/9620>`_. Security Fix: Broker Credential Leak Prevention ------------------------------------------------ Fixed a security issue where broker URLs containing passwords were being logged in plaintext by the delayed delivery mechanism. Broker credentials are now properly sanitized in all log output. Contributed by `@giancarloromeo <https://github.com/giancarloromeo>`_ in `#9997 <https://github.com/celery/celery/pull/9997>`_. Memory Leak Fixes ----------------- Two significant memory leaks have been fixed in this release: **Exception Handling Memory Leak**: Fixed a critical memory leak in task exception handling that was particularly severe on Python 3.11+ due to enhanced traceback data. The fix properly breaks reference cycles in tracebacks to allow garbage collection. Contributed by `@jaiganeshs21 <https://github.com/jaiganeshs21>`_ in `#9799 <https://github.com/celery/celery/pull/9799>`_. **Pending Result Memory Leak**: Fixed a memory leak where ``AsyncResult`` subscriptions were not being cleaned up when results were forgotten. Contributed by `@tsoos99dev <https://github.com/tsoos99dev>`_ in `#9806 <https://github.com/celery/celery/pull/9806>`_. ETA Task Memory Limit --------------------- New configuration option :setting:`worker_eta_task_limit` to prevent out-of-memory crashes when workers fetch large numbers of ETA or countdown tasks. Previously, workers could exhaust available memory when the broker contained many scheduled tasks. Example usage: .. code-block:: python app.conf.worker_eta_task_limit = 1000 Contributed by `@sashu2310 <https://github.com/sashu2310>`_ in `#9853 <https://github.com/celery/celery/pull/9853>`_. Queue Type Selection for Auto-created Queues -------------------------------------------- New configuration options allow specifying the queue type and exchange type when Celery auto-creates missing queues. This is particularly useful for RabbitMQ users who want to use quorum queues with auto-created queues. Configuration options: - :setting:`task_create_missing_queue_type`: Sets the queue type for auto-created queues (e.g., ``quorum``, ``classic``) - :setting:`task_create_missing_queue_exchange_type`: Sets the exchange type for auto-created queues Example usage: .. code-block:: python app.conf.task_create_missing_queue_type = 'quorum' Contributed by `@ghirailghiro <https://github.com/ghirailghiro>`_ in `#9815 <https://github.com/celery/celery/pull/9815>`_.

I would expect `typing_extensions.Doc` to be deprecated and then removed at some point from `typing_extensions`, for that reason there's the new `annotated-doc` micro-package. If you are curious about this, you can read more in the repo for [`annotated-doc`](https://github.com/fastapi/annotated-doc). This new version `0.120.0` only contains that transition to the new home package for that utility class `Doc`. ##### Translations - 🌐 Sync German docs.

And with this, support for **Pydantic v1 is now deprecated** and will be **removed** from FastAPI in a future version soon. **Note**: have in mind that the Pydantic team already stopped supporting Pydantic v1 for recent versions of Python, starting with Python 3.14. You can read in the docs more about how to [Migrate from Pydantic v1 to Pydantic v2](https://fastapi.tiangolo.com/how-to/migrate-from-pydantic-v1-to-pydantic-v2/). ##### Features - ✨ Add support for `from pydantic.v1 import BaseModel`, mixed Pydantic v1 and v2 models in the same app. MR [#14168](https://github.com/fastapi/fastapi/pull/14168) by [@tiangolo](https://github.com/tiangolo). ### [`v0.118.3`](https://github.com/fastapi/fastapi/releases/tag/0.118.3) [Compare Source](https://github.com/fastapi/fastapi/compare/0.118.2...0.118.3) ##### Upgrades - ⬆️ Add support for Python 3.14.

MR [#14125](https://github.com/fastapi/fastapi/pull/14125) by [@YuriiMotov](https://github.com/YuriiMotov). ### [`v0.118.0`](https://github.com/fastapi/fastapi/releases/tag/0.118.0) [Compare Source](https://github.com/fastapi/fastapi/compare/0.117.1...0.118.0) ##### 0.118.0 ##### Fixes - 🐛 Fix support for `StreamingResponse`s with dependencies with `yield` or `UploadFile`s, close after the response is done. MR [#14099](https://github.com/fastapi/fastapi/pull/14099) by [@tiangolo](https://github.com/tiangolo). Before FastAPI 0.118.0, if you used a dependency with `yield`, it would run the exit code after the *path operation function* returned but right before sending the response. This change also meant that if you returned a `StreamingResponse`, the exit code of the dependency with `yield` would have been already run. For example, if you had a database session in a dependency with `yield`, the `StreamingResponse` would not be able to use that session while streaming data because the session would have already been closed in the exit code after `yield`. This behavior was reverted in 0.118.0, to make the exit code after `yield` be executed after the response is sent. You can read more about it in the docs for [Advanced Dependencies - Dependencies with `yield`, `HTTPException`, `except` and Background Tasks](https://fastapi.tiangolo.com/advanced/advanced-dependencies#dependencies-with-yield-httpexception-except-and-background-tasks). Including what you could do if you wanted to close a database session earlier, before returning the response to the client. ##### Docs - 📝 Update `tutorial/security/oauth2-jwt/` to use `pwdlib` with Argon2 instead of `passlib`.
