From 4.0.0 until 4.12.0, ViewComponent::Base instances retain render-scoped objects across calls to render_in; if the same component, collection, or spacer component instance is reused across requests, users, tenants, or threads, later renders can use stale helpers, controller, request, view_flow, format\/variant details, and slot child context from an earlier render. This can cause authorization-aware components to render privileged UI for a lower-privileged user, generate links using a stale Host header, leak slot\/helper state, and mix request context under concurrent rendering. This issue is fixed in version 4.12.0.<\/p>\n<p>  Severity: 6.8 | MEDIUM<\/p>\n<p>  Visit the link for more details, such as CVSS details, affected products, timeline, and more&#8230;\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"<p>CVE ID :CVE-2026-54497 Published : July 17, 2026, 9:17 p.m. | 21\u00a0minutes ago Description :view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails.
