- Cache invalid license statuses with 30s TTL to prevent DoS amplification
- Return LicenseStatus enum (not raw str) from get_cached_license_status
- Flatten nested try/except into _read_cached_license_status / _fetch_and_cache_license_status helpers
- Escalate log levels from debug to warning with exc_info for cache failures
- Switch before_request license check from fail-open to fail-closed
- Remove dead raise_for_status parameter from BaseRequest.send_request
- Gate license expired_at behind is_authenticated; only expose status to unauthenticated callers (CVE-2025-63387)
- Remove redundant 'not is_console_api' guard in before_request
- Add 8 unit tests for get_cached_license_status
Replace raw license status strings with LicenseStatus enum values in
app_factory.py and enterprise_service.py to prevent silent mismatches.
Use trailing-slash prefixes ('/console/api/', '/api/') to avoid false
matches on unrelated paths like /api-docs.
After force-logout due to license expiry, the login page calls
/system-features without auth. The license block was gated behind
is_authenticated, so the frontend always saw status='none' instead
of the actual expiry status. Split the guard so license.status and
expired_at are always returned while workspace usage details remain
auth-gated.
Cache license status for 10 minutes to reduce HTTP calls to enterprise API.
Only caches license status, not full system features.
Changes:
- Add EnterpriseService.get_cached_license_status() method
- Cache key: enterprise:license:status
- TTL: 600 seconds (10 minutes)
- Graceful degradation: falls back to API call if Redis fails
Performance improvement:
- Before: HTTP call (~50-200ms) on every API request
- After: Redis lookup (~1ms) on cached requests
- Reduces load on enterprise service by ~99%
When enterprise API returns 403/404, the response contains error JSON
instead of expected data structure. Code was accessing fields directly
causing KeyError → 500 Internal Server Error.
Changes:
- Add enterprise-specific error classes (EnterpriseAPIError, etc.)
- Implement centralized error validation in EnterpriseRequest.send_request()
- Extract error messages from API responses (message/error/detail fields)
- Raise domain-specific errors based on HTTP status codes
- Preserve backward compatibility with raise_for_status parameter
This prevents KeyError crashes and returns proper HTTP error codes
(403/404) instead of 500 errors.
