CVE-2024-51775Network attack vector

Cross-origin paragraph disclosure via unchecked WebSocket Origin

Published Aug 3, 2025 · Updated Nov 4, 2025

Missing Origin validation in Apache Zeppelin 0.11.1 allows remote attackers to read internal paragraph information through WebSockets. The terminal-interpreter WebSocket handshake accepts connections without validating the Origin header against a trusted source. Network reachability to the server is sufficient; the published impact is limited to paragraph information, with no command execution established.
