Add SubscriptionCredentialsSerializer (PlainSerializerCleanTextMixin) for /api/v2/config/subscriptions/ so POST requests validate credential string fields through the CleanText enforcement pipeline.

  • subscriptions_client_id, subscriptions_username: Tier 2 (free-text)
  • subscriptions_client_secret, subscriptions_password: excluded (secrets)
  • name_fields = frozenset() ensures Tier 2, not Tier 1
  • Fake Meta.model satisfies CleanTextMixin audit logging and OPTIONS metadata
  • ApiV2SubscriptionView gains serializer_class and get_serializer() so the existing metadata machinery advertises validation patterns on OPTIONS
  • post() runs serializer.is_valid() before credential logic, preserving all existing error messages, status codes, and $encrypted$ handling
  • Functional tests: unsafe-input rejection, secret exclusion, safe passthrough, OPTIONS pattern presence/absence, all existing happy/error paths still pass

STEPS TO REPRODUCE AND EXTRA INFO

Summary by CodeRabbit

  • New Features

    • The subscriptions settings endpoint now exposes its available fields more consistently in API metadata.
    • When enhanced validation is enabled, its OPTIONS response includes clean-text validation patterns for applicable fields.
    • Leading and trailing whitespace is preserved in subscription credential values.
    • Unused client credential fields can be submitted as explicit null values.
  • Bug Fixes

    • Unsafe input is rejected for subscription client ID and username fields.
    • Secret fields remain exempt from clean-text validation.

📝 Walkthrough

Walkthrough

The subscription endpoint now validates POST credentials through a serializer. The serializer defines four optional fields and supports CleanText metadata. Functional tests cover credential validation, whitespace preservation, null client credentials, and OPTIONS patterns.

Changes

DRF CharField strips leading/trailing whitespace by default, which
silently altered subscription credentials before passing them to
validate_rh. Set trim_whitespace=False on all four credential fields
so serializer.validated_data preserves the exact submitted values.

Add four regression tests proving whitespace is passed unchanged to
validate_rh for username, password, client_id, and client_secret.

Add docstrings to concrete_model(), check_permissions(), post(), and
the ApiV2SubscriptionView class to meet the 80% docstring coverage
threshold.

Comment thread awx/api/serializers.py Outdated
DRF CharField rejects explicit JSON null by default, causing a 400
"This field may not be null" error when a frontend sends null for the
unused credential pair (e.g. client_id=null, client_secret=null with a
valid username/password). Add allow_null=True on all four optional
fields so the serializer passes null through to the view, where the
existing falsy-check credential-selection logic already handles it
correctly.

Includes a focused regression test proving a valid username/password
pair with null client fields is accepted and calls validate_rh with
the basic-auth pair.

I found one audit-traceability concern in the new validation path:

ApiV2SubscriptionView.get_serializer() returns self.serializer_class(*args, **kwargs) without supplying request/view context, and post() directly constructs self.serializer_class(data=request.data).

CleanTextMixin accesses the request with self.context.get('request'), so missing context does not raise or prevent unsafe input from being rejected. However, the resulting warning omits the for user … and (ip …) attribution, reducing traceability for rejected subscription credential input.

Could this path construct the serializer through self.get_serializer(data=request.data) and have get_serializer() supply the standard request/view context? A regression assertion that the rejection warning includes the user and client IP would also cover this behavior.


AI-generated. Review for accuracy.

…tialsSerializer

ApiV2SubscriptionView.get_serializer() now injects the standard DRF
serializer context (request, format, view) so that CleanTextMixin's
_log_validation_failure() can attribute rejected input to the
authenticated user and client IP.

post() is updated to call self.get_serializer(data=request.data)
instead of constructing the serializer class directly, ensuring
consistent context propagation.

A focused regression test asserts that the CleanText warning emitted
for unsafe subscription input includes the authenticated username
and client IP address.
