Bump view_component from 4.6.0 to 4.12.0

[dependabot]

Bumps view_component from 4.6.0 to 4.12.0.

Release notes

Sourced from view_component's releases.

4.12.0

• Fix stale render context on reused component instances. A ViewComponent::Base instance memoized its controller, helpers, request, view context, lookup context, view flow, and requested format details on first render via ||=. Rendering the same instance a second time (intentionally or via aliasing) reused that stale context, which could leak data across requests, sessions, or users. #render_in now resets these ivars on every call so each render derives its context from the current view.

  Joel Hawksley

• Fix HTML-safety bypass in around_render. ViewComponent::Base#around_render could return HTML-unsafe strings that bypassed the escaping applied to normal #call return values, creating an XSS risk. The vulnerability was amplified in ViewComponent::Collection#render_in, which joined per-item results and unconditionally marked the output html_safe. HTML-unsafe strings returned from around_render are now escaped (with a warning) and Collection#render_in now uses safe_join so unsafe per-item output is escaped instead of laundered into a SafeBuffer. Joel Hawksley

4.11.0

• Update render_in signature to accept **_ for compatibility with Rails #50623.

  Joel Hawksley

• Fix translation scope resolution in nested lambda-backed slots. Relative t(".key") calls inside lambda-backed slots were resolving against an intermediate component's scope instead of the original partial's scope where the block was defined.

  Artin Boghosian

4.10.0

• Fix NameError: uninitialized constant ViewComponent::SystemTestControllerNefariousPathError when booting in the test environment with eager_load = true.

  Joel Hawksley

• Fix yielded content rendered at wrong location when using form helpers.

  Joel Hawksley, Markus

4.9.0

• Fix path traversal vulnerability in ViewComponentsSystemTestController where sibling directories sharing a string prefix with the allowed temp directory could bypass the path containment check. The start_with? check has been replaced with a separator-aware prefix check, and nefarious path errors now return a 404 instead of an unhandled exception.

  Joel Hawksley

• Fix preview route vulnerability where inherited methods on ViewComponent::Preview (such as render_with_template) could be invoked via the preview URL, allowing arbitrary internal Rails templates to be rendered with attacker-controlled locals and request parameters. render_args now raises AbstractController::ActionNotFound for any example not explicitly declared on the preview subclass.

  Joel Hawksley

• Add yard-lint to CI.

  Joel Hawksley

4.8.0

• Add compile.view_component ActiveSupport::Notifications event for eager compilation at boot time.

  Joel Hawksley, GitHub Copilot

4.7.0

• Fix stale content cache when slots are accessed before render_in.

  Jared Armstrong

• Add rubocop-view_component to resources.
