Active Storage

• Disable libvips's unfuzzed image loaders and savers.

  libvips flags some of its loaders and savers as "unfuzzed" or "untrusted", meaning they are only safe for trusted content. Active Storage will call Vips.block_untrusted(true) to disable them while booting. An application that needs a specific loader or saver may re-enable it in an initializer.

Changelog

Sourced from activestorage's changelog.

Rails 8.1.3.1 (July 29, 2026)

• Disable libvips's unfuzzed image loaders and savers.

  libvips flags some of its loaders and savers as "unfuzzed" or "untrusted", meaning they are only safe for trusted content. Active Storage will call Vips.block_untrusted(true) to disable them while booting. An application that needs a specific loader or saver may re-enable it in an initializer.

  This is a breaking change for applications that process image types with an unfuzzed loader or saver. Variant transformation of BMP, ICO, and PSD attachments will raise Vips::Error, and analysis of these and other types such as SVG, JPEG XL, JPEG 2000, and Netpbm will no longer record width and height. Requesting an unfuzzed output format, typically FITS, JXL, or anything delegated to ImageMagick, will also raise Vips::Error. Attaching, storing, and downloading are unchanged.

  An application seeing Vips::Error raised during image transformation may wish to remove the affected content types from config.active_storage.variable_content_types in an initializer. Active Storage will then treat those attachments as not variable and will not generate variants for them. This most often matters to an application that transforms images during a request rather than in a background job, where the failure surfaces as an error response instead of a failed job.

  Rails.application.config.active_storage.variable_content_types -=
    %w[ image/bmp image/vnd.microsoft.icon image/vnd.adobe.photoshop ]

  Applications using the :mini_magick variant processor will see no change in how their attachments are processed, but the loaders and savers will be disabled process-wide whenever ruby-vips is installed, and the version requirements below will still apply. Such an application may remove ruby-vips from its Gemfile to avoid both.

  The minimum supported version of libvips is now 8.13, and the minimum supported version of ruby-vips is now 2.2.1. These are the earliest versions that are capable of disabling untrusted operations. When ruby-vips is installed and either minimum is not met, Active Storage will raise a RuntimeError while booting rather than run in an unsecurable environment.

Updates loofah from 2.25.1 to 2.25.2

Release notes

Sourced from loofah's releases.

2.25.2 / 2026-07-15

Security

• Ensure Loofah::HTML5::Scrub.allowed_uri? recognizes numeric character references without semicolons (e.g. javascript&#58alert(1)), which browsers decode and execute, and rejects schemes split by them. See GHSA-5qhf-9phg-95m2. @​flavorjones
• Ensure Loofah::HTML5::Scrub.allowed_uri? recognizes the named character references 	 and 
, which CGI.unescapeHTML does not decode and browsers strip from URIs, and rejects schemes split by them (e.g. java	script:alert(1)). See GHSA-8whx-365g-h9vv. @​flavorjones
• Ensure that both href and xlink:href attributes on SVG elements like use are restricted to local (same-document) references. Previously only xlink:href was restricted, allowing the SVG 2 href attribute to reference external documents. See GHSA-9wjq-cp2p-hrgf. @​flavorjones

Improved

• Harden data: URI mediatype parsing in Loofah::HTML5::Scrub.allowed_uri?. The mediatype is now parsed following the WHATWG data: URL spec and RFC 2397 instead of simply being split on a colon. A data: URI with an omitted or malformed mediatype is now treated as text/plain and allowed, and one without the required comma is now rejected. #305 @​flavorjones
• Remove feed from the default set of allowed protocols. The feed URI scheme was never accepted as a standard protocol, and no major browser supports it. Removing it reduces the attack surface particularly for non-browser contexts. #304 @​flavorjones
• Remove a vestigial &#x70 alternative from Loofah::HTML5::SafeList::PROTOCOL_SEPARATOR. This appears to be an ancient typo dating back to pre-extraction Rails circa 2007. #305 @​flavorjones

Updates rails-html-sanitizer from 1.7.0 to 1.7.1

Release notes

Sourced from rails-html-sanitizer's releases.

v1.7.1 / 2026-07-15

• SVG reference elements now restrict both href and xlink:href to local references.

  Previously PermitScrubber restricted only xlink:href on elements in SVG_ALLOW_LOCAL_HREF, so a plain href attribute on those elements could reference an external document. Applications are only affected if the allowed tags are overridden to include an SVG reference element such as use; the default configuration is not affected.

  This change addresses GHSA-cj75-f6xr-r4g7 (CVE requested). The minimum Loofah dependency is now ~> 2.25, >= 2.25.2.
