"statement": "React Router (npm packages react-router and react-router-dom) versions 7.11.0 through 7.17.0 contain a missing protocol validation flaw in the RSCErrorHandler component. This component is only used by applications that opt in to React Router's unstable React Server Components (RSC) APIs; applications that do not use the RSC APIs are not reachable through this code path. Where the RSC APIs are in use, an attacker can supply a URL that bypasses protocol validation and redirect a victim to an untrusted external site, which can facilitate phishing or information disclosure. This issue is fixed upstream in react-router/react-router-dom 7.18.0.\nThis flaw is only reachable in Red Hat products that both bundle an affected version of react-router/react-router-dom in a web console or UI component AND make use of the unstable RSC APIs in that component's own code. Simply bundling react-router as a dependency does not by itself make a product exploitable; each console/UI must be independently assessed by its owning component team for RSC API usage.\nRed Hat's CVSS score (6.9, AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:L/A:N) matches the upstream/CVE.org self-assigned score exactly, so no Red Hat-specific re-scoring was applied.", "threat_severity": "Moderate"}
