CVE-2026-54498
view_component: around_render HTML-Safety Bypass
HIGH 8.7EPSS 0.5%
view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. From 4.0.0 until 4.12.0, ViewComponent::Base#around_render can return HTML-unsafe strings that bypass the escaping behavior applied to normal #call return values. This creates an XSS risk when downstream applications use around_render to wrap, replace, instrument, or conditionally return content that includes user-controlled data, and ViewComponent::Collection#render_in can amplify the issue by joining per-item results and marking the entire output html_safe, converting raw unsafe output into an ActiveSupport::SafeBuffer. This issue is fixed in version 4.12.0.
