Merge Risk: 🟡 Moderate · up to The exporter can lose account identity and check timestamps, emit incorrect control mappings, reject valid finding data through schema-invalid output, and concatenate multiple exports into invalid JSON.

Emit existing NIST SP 800-53 Rev. 5 IDs through the OSCAL control-reference/target structure required by the issue.

Make the result UUID unique per export.
result_uuid derives from account_uid only, so every scan of the same account emits the same results[0].uuid. The PR objectives require result identity to be unique per export while internal references stay stable. Consumers that key results by UUID will treat separate scans as the same result and merge or overwrite history.

jsonschema Python library public API to override the pattern keyword with a custom regex implementation
💡 Result:
To override the pattern keyword in the jsonschema Python library, you must create a custom validator class using the jsonschema.validators.extend function [1][2][3]. The jsonschema library allows you to define a custom validator callable for any keyword [1]. When you provide a new callable with the same name as an existing keyword (such as pattern), it will silently replace the default implementation [1][3]. To implement this: 1. Define a custom validation function that accepts the validator instance, the value of the pattern keyword, the instance being validated, and the schema [1][2]. 2. Use jsonschema.validators.extend to create a new validator class that includes your custom pattern validator in its validators mapping [2][3]. Example implementation pattern: import jsonschema from jsonschema.validators import validator_for def custom_pattern_validator(validator, pattern, instance, schema): # Your custom regex logic here, e.g., using the 'regex' library import regex if not regex.search(pattern, instance): yield jsonschema.ValidationError(f"{instance!r} does not match custom pattern {pattern!r}") # Create a custom validator class based on an existing draft MyValidator = jsonschema.validators.extend( jsonschema.Draft202012Validator, {"pattern": custom_pattern_validator}) # Use your custom validator MyValidator(schema={...}).validate(instance={...}) Note that overriding pattern also affects patternProperties [4]. If you require consistency, you should also override the patternProperties keyword in the same validator extension [4]. For more complex use cases where you need to support custom behavior across metaschema validation and format checking, you may need to implement a more comprehensive validator subclass, as noted in library discussions regarding custom regex engines [4].

CI was failing on ruff-linting (blocking Unit Tests Complete and every
downstream test job). Fixed the 13 flagged style violations, 11 via
`ruff --fix`, 2 applied manually after review (ternary conversion, set
literal for membership testing).
While reviewing the two manual fixes, found a real bug beyond lint:
target_status = target.get("status", "") assumed `status` is always a
string, then called target_status.lower(). But the OSCAL 1.2.3 schema
defines finding.target.status as a required OBJECT --
{"state": "satisfied"|"not-satisfied", "reason": "pass"|"fail"|"other"}
-- not a string. Proved this is a real, live interoperability break, not
theoretical: fed this parser the actual output of a just-fixed OSCAL
exporter (prowler-cloud/prowler#12475, which now correctly emits the
object-shaped status per the same schema) and it crashed with
AttributeError: 'dict' object has no attribute 'lower'. Any OSCAL
producer that emits a schema-compliant document would fail to import
here.
Added _is_failed(), which handles both shapes: the correct object shape
(checking state/reason), a bare string (matching this repo's existing
test fixtures, for looser/legacy producers), and target.status being
absent entirely (falls back to the finding-level status prop, matching
the original intent).
Re-ran the exact prowler-output-crashes-this-parser reproduction after
the fix: now parses successfully. Added 3 regression tests (not-
satisfied -> active, satisfied -> mitigated, missing target.status ->
falls back to props) alongside the 4 existing tests (7/7 passing).
ruff clean.

Took a close look at this — nice work getting the OSCAL 1.2.3 schema conformance right (validating against the real official schema rather than just Two things beyond schema conformance worth considering before merge, since a JSON-schema validator can't catch either (both are UUID format-valid but semantically off): 1. result_uuid = str(uuid.uuid5(uuid.NAMESPACE_DNS, f"prowler.result.{account_uid}"))This is derived only from Possible fix: derive 2. The transform doesn't use Prowler's own account_uid = getattr(first_finding, "account_uid", "default-account")
resource_uid = getattr(finding, "resource_uid", "resource-default")
check_id = finding.metadata.CheckID if hasattr(...) else "check_id"
This is also why the test suite mocks findings with Neither of these blocks the schema-conformance work you already did — just flagging before this merges, since both would be more awkward to fix once consumers depend on the current UUID/field behavior. (Side note, unrelated to the code: the PR's conflict-checker shows |
CodeRabbit fetched the real NIST OSCAL 1.2.3 reference and flagged:
Observation emits "observation-uuid" instead of required "uuid", so
related-observation references cannot resolve; OscalFinding omits
required "uuid" and emits unsupported "collected"; target.target-id was
set to the finding's own uuid instead of the assessed objective; and
only json.loads() was tested, never real schema validation.
I verified every claim -- and found two more real bugs the review
didn't catch -- by downloading the actual official schema
(github.com/usnistgov/OSCAL release v1.2.3) and validating the real
serialized output against it with jsonschema:
8 schema errors on the unfixed code, including two CodeRabbit never
flagged: Subject.description is not an allowed property on
subject-reference (additionalProperties: false), and Result is
missing the entirely-required `reviewed-controls` block. Also found
that finding-target.status is required (not just target-id) and that
the schema's TokenDatatype pattern rejects a raw UUID as target-id
(must start with a letter/underscore) -- confirming check_id, not a
generated uuid, is the correct target-id.
Fixes, each verified against the real official schema (0 errors after,
for PASS-only, FAIL, and mixed documents):
- Observation.to_dict(): "observation-uuid" -> "uuid"
- OscalFinding: now emits its own "uuid"; "collected" removed (not a
valid finding property -- that field exists only on observation);
target now carries {type: "objective-id", target-id: check_id,
status: {state, reason}} instead of reusing finding_uuid as target-id
with no status at all
- Subject.to_dict(): "description" removed (not an allowed property on
subject-reference; kept as a constructor field for callers, just not
serialized)
- Result.to_dict(): now emits the required "reviewed-controls" with an
include-all control-selection
- Result.to_dict(): "observations"/"findings" are now omitted entirely
when empty rather than emitted as [] (both have schema minItems: 1)
Added a pinned copy of the real official schema
(tests/lib/outputs/oscal/fixtures/) and real jsonschema-based validation
tests for both a PASS-only document and a mixed PASS+FAIL document, per
CodeRabbit's ask for "PASS and FAIL schema-validation tests" -- not just
json.loads(). The official schema uses \p{L}/\p{N} Unicode-property regex
(valid ECMA-262, per the JSON Schema spec) that Python's stdlib `re`
doesn't support; the `regex` package (added to dev deps) is a compatible
drop-in, patched into jsonschema's pattern-matching for the test only.
Also added the requested Google-style docstrings across both files.
7/7 tests pass (2 pre-existing, 5 new). black clean. flake8 clean under
the project's actual configured ignores (.pre-commit-config.yaml); one
E402 in the test file predates this change (confirmed against HEAD) and
is left untouched as out of scope.

Reject or partition mixed-account findings.
OSCAL.transform() accepts any non-empty List[Finding] and derives the document and result account/provider metadata from findings[0]. Observation properties do not include account or provider identity. Mixed-account or mixed-provider input therefore applies the first finding's metadata to the export and loses the other identities.
Partition findings by account and provider, or reject lists with non-uniform identities.

Preserve integer finding timestamps.
Finding.generate_output passes the configured check timestamp through fill_common_finding_data. When unix_timestamp is enabled, outputs_unix_timestamp converts it to integer Unix seconds. The OSCAL branch then replaces that value with now_iso, so the export records export time instead of check time.
Convert integer timestamps before serialization:
