Full changelog

UI

🐞 Fixed

  • Large scan report ZIP downloads now stream through a Next.js Route Handler instead of buffering the full file in a Server Action (#11330)
  • Compliance requirement findings table now respects the page size selector (#11365)

API

🐞 Fixed

  • finding-groups slow response with finding-level filters such as region; check title and description are now read from the daily summaries, which drops sorting by check_title (#11326)

SDK

🐞 Fixed

  • compute_project_os_login_enabled and compute_project_os_login_2fa_enabled checks for GCP provider no longer false-FAIL on projects where the enable-oslogin / enable-oslogin-2fa metadata is not set explicitly but is inherited automatically from the constraints/compute.requireOsLogin org policy. The policy controller writes the inherited value in lowercase ("true"), but the service-layer parser compared it to the uppercase string literal "TRUE". Comparison is now case-insensitive (#11341)
  • storage_smb_channel_encryption_with_secure_algorithm check for Azure provider no longer passes when a storage account allows a weak SMB channel encryption algorithm (e.g. AES-128-CCM/AES-128-GCM) alongside AES-256-GCM; it now requires every enabled algorithm to be in the recommended list, configurable via azure.recommended_smb_channel_encryption_algorithms (defaults to AES-256-GCM only, as required by CIS) (#11327)
  • Azure and M365 providers crashing with RuntimeError: There is no current event loop on Python 3.12 when called from threads without an active event loop (e.g. Celery workers) (#11360)

MCP

🐞 Fixed

  • Preserve authorization header in HTTP mode (#11366)
