Overview
Affected versions of this package are vulnerable to Access Control Bypass in the render_in. An attacker can access sensitive information or perform unauthorized actions by exploiting stale render context, which may include helpers, controller, request, view_flow, format/variant details, and slot child context from previous renders. This can result in privileged UI being rendered for lower-privileged users, generation of links with outdated Host headers, leakage of slot/helper state, and mixing of request context during concurrent rendering.
