Rails 8.1.3 (March 24, 2026)

• Fix ActiveStorage::Blob content type predicate methods to handle nil.

  Daichi KUDO

Rails 8.1.2.1 (March 23, 2026)

• Filter user supplied metadata in DirectUploadController

  [CVE-2026-33173]

  Jean Boussier

• Configurable maxmimum streaming chunk size

  Makes sure that byte ranges for blobs don't exceed 100mb by default. Content ranges that are too big can result in denial of service.

  [CVE-2026-33174]

  Gannon McGibbon

• Limit range requests to a single range

  [CVE-2026-33658]

  Jean Boussier

• Prevent path traversal in DiskService.

  DiskService#path_for now raises an InvalidKeyError when passed keys with dot segments (".", ".."), or if the resolved path is outside the storage root directory.

  #path_for also now consistently raises InvalidKeyError if the key is invalid in any way, for example containing null bytes or having an incompatible encoding. Previously, the exception raised may have been ArgumentError or Encoding::CompatibilityError.

  DiskController now explicitly rescues InvalidKeyError with appropriate HTTP status codes.

  [CVE-2026-33195]

• Prevent glob injection in DiskService#delete_prefixed.

  Escape glob metacharacters in the resolved path before passing to Dir.glob.

  Note that this change breaks any existing code that is relying on delete_prefixed to expand glob metacharacters. This change presumes that is unintended behavior (as other storage services do not respect these metacharacters).

  [CVE-2026-33202]

Rails 8.1.2 (January 08, 2026)

• Restore ADC when signing URLs with IAM for GCS

  ADC was previously used for automatic authorization when signing URLs with IAM. Now it is again, but the auth client is memoized so that new credentials are only requested when the current ones expire. Other auth methods can now be used instead by setting the authorization on ActiveStorage::Service::GCSService#iam_client.

  ActiveStorage::Blob.service.iam_client.authorization = Google::Auth::ImpersonatedServiceAccountCredentials.new(options)
  

  This is safer than setting Google::Apis::RequestOptions.default.authorization because it only applies to Active Storage and does not affect other Google API clients.

• No changes.

Rails 8.1.0 (October 22, 2025)

• Add structured events for Active Storage:

  • active_storage.service_upload
  • active_storage.service_download
  • active_storage.service_streaming_download
  • active_storage.preview
  • active_storage.service_delete
  • active_storage.service_delete_prefixed
  • active_storage.service_exist
  • active_storage.service_url
  • active_storage.service_mirror

  Gannon McGibbon

• Allow analyzers and variant transformer to be fully configurable

  # ActiveStorage.analyzers can be set to an empty array:
  config.active_storage.analyzers = []
  # => ActiveStorage.analyzers = []
  
  # or use custom analyzer:
  config.active_storage.analyzers = [ CustomAnalyzer ]
  # => ActiveStorage.analyzers = [ CustomAnalyzer ]
  

  If no configuration is provided, it will use the default analyzers.

  You can also disable variant processor to remove warnings on startup about missing gems.

  config.active_storage.variant_processor = :disabled

• Remove deprecated :azure storage service.

  Rafael Mendonça França

• Remove unnecessary calls to the GCP metadata server.

  Calling Google::Auth.get_application_default triggers an explicit call to the metadata server - given it was being called for significant number of file operations, it can lead to considerable tail latencies and even metadata server overloads. Instead, it's preferable (and significantly more efficient) that applications use:

  Google::Apis::RequestOptions.default.authorization = Google::Auth.get_application_default(...)
  

  In the cases applications do not set that, the GCP libraries automatically determine credentials.

  This also enables using credentials other than those of the associated GCP service account like when using impersonation.

• Direct upload progress accounts for server processing time.

• Delegate ActiveStorage::Filename#to_str to #to_s

  Supports checking String equality:

  filename = ActiveStorage::Filename.new("file.txt")
  filename == "file.txt" # => true
  filename in "file.txt" # => true
  "file.txt" == filename # => true

• A Blob will no longer autosave associated Attachment.

  This fixes an issue where a record with an attachment would have its dirty attributes reset, preventing your after commit callbacks on that record to behave as expected.

  Note that this change doesn't require any changes on your application and is supposed to be internal. Active Storage Attachment will continue to be autosaved (through a different relation).
