CVE-2025-61668Network attack vector

Unauthenticated server crash via unchecked error response

Published Oct 2, 2025 · Updated Oct 2, 2025

Denial of service in Plone Volto allows remote attackers to crash the NodeJS frontend server by requesting a crafted URL without authentication. The API Redux middleware's error path dereferences error.response.body.message without first ensuring that error.response and its body exist, causing an uncaught exception. Any anonymous network client that can reach the frontend can trigger the process exit, interrupting service until the NodeJS process restarts.
