CVE-2026-44514Network attack vector

Log disclosure via missing WebSocket origin validation

Published May 14, 2026 · Updated May 14, 2026

Cross-site WebSocket hijacking in Kubetail Dashboard before 0.14.0 and CLI before 0.16.0 allows remote attackers to read logs. The dashboard's WebSocket upgrade handlers accept cross-origin requests without adequately validating Origin, letting an attacker-controlled page open a log stream with the browser's ambient session or basic-auth credentials. Exploitation requires an authenticated user to visit that page and the attacker to know the dashboard URL; access is read-only and limited to Kubernetes logs available to that user.
