## Rails 7.2.3.1 (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]

    *Mike Dalessio*

*   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]

    *Mike Dalessio*


## Rails 7.2.3 (October 28, 2025) ##

*   Fix `config.active_storage.touch_attachment_records` to work with eager loading.

    *fatkodima*

*   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).

    *Edouard-chin*


## Rails 7.2.2.2 (August 13, 2025) ##

*   Remove dangerous transformations

    [CVE-2025-24293]

    *Zack Deveau*

*   No changes.


## Rails 7.2.1.2 (October 23, 2024) ##

## Rails 7.2.1.1 (October 15, 2024) ##

*   No changes.


## Rails 7.2.1 (August 22, 2024) ##

*   No changes.


## Rails 7.2.0 (August 09, 2024) ##

*   Remove deprecated `config.active_storage.silence_invalid_content_types_warning`.

    *Rafael Mendonça França*

*   Remove deprecated `config.active_storage.replace_on_assign_to_many`.

    *Rafael Mendonça França*

*   Add support for custom `key` in `ActiveStorage::Blob#compose`.

    *Elvin Efendiev*

*   Add `image/webp` to `config.active_storage.web_image_content_types` when `load_defaults "7.2"`
    is set.

    *Lewis Buckley*

*   Fix JSON-encoding of `ActiveStorage::Filename` instances.

    *Jonathan del Strother*

*   Fix N+1 query when fetching preview images for non-image assets.

    *Aaron Patterson & Justin Searls*

*   Fix all Active Storage database related models to respect
    `ActiveRecord::Base.table_name_prefix` configuration.

    *Chedli Bourguiba*

*   Fix `ActiveStorage::Representations::ProxyController` not returning the proper
    preview image variant for previewable files.

    *Chedli Bourguiba*

*   Fix `ActiveStorage::Representations::ProxyController` to proxy untracked
    variants.

    *Chedli Bourguiba*

*   When using the `preprocessed: true` option, avoid enqueuing transform jobs
    for blobs that are not representable.

    *Chedli Bourguiba*

*   Prevent `ActiveStorage::Blob#preview` to generate a variant if an empty variation is passed.

    Calls to `#url`, `#key` or `#download` will now use the original preview
    image instead of generating a variant with the exact same dimensions.

    *Chedli Bourguiba*

*   Process preview image variant when calling `ActiveStorage::Preview#processed`.

    For example, `attached_pdf.preview(:thumb).processed` will now immediately
    generate the full-sized preview image and the `:thumb` variant of it.
    Previously, the `:thumb` variant would not be generated until a further call
    to e.g. `processed.url`.

    *Chedli Bourguiba* and *Jonathan Hefner*

*   Prevent `ActiveRecord::StrictLoadingViolationError` when strict loading is
    enabled and the variant of an Active Storage preview has already been
    processed (for example, by calling `ActiveStorage::Preview#url`).

    *Jonathan Hefner*

*   Fix `preprocessed: true` option for named variants of previewable files.

    *Nico Wenterodt*

*   Allow accepting `service` as a proc as well in `has_one_attached` and `has_many_attached`.

    *Yogesh Khater*
