React Router is a router for React. In @remix-run/react version prior to 2.17.3. and react-router 7.0.0 through 7.11.0, a XSS vulnerability exists in in React Router's <ScrollRestoration> API in Framework Mode when using the getKey/storageKey props during Server-Side Rendering which could allow arbitrary JavaScript execution during SSR if untrusted content is used to generate the keys. There is no impact if server-side rendering in Framework Mode is disabled, or if Declarative Mode (<BrowserRouter>) or Data Mode (createBrowserRouter/<RouterProvider>) is being used. This issue has been patched in @remix-run/react version 2.17.3 and react-router version 7.12.0.

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:3958 advisory.

    Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing     IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to     individual teams, while automation developers retain the freedom to write tasks that leverage existing     knowledge without the overhead. Ansible Automation Platform makes it possible for users across an     organization to share, vet, and manage automation content by means of a simple, powerful, and agentless     language.
