CVE-2026-47723Network attack vector

Administrative action manipulation via missing frame restrictions

Published Jul 23, 2026 · Updated Jul 23, 2026

Clickjacking in nebula-mesh before 0.3.1 allows remote attackers to manipulate administrative actions through framed UI pages. The top-level HTTP handler returns every Web UI and API response without CSP frame-ancestors or X-Frame-Options restrictions. Exploitation requires an administrator to browse and interact with a framed operator-management or CA-management page, exposing certificate signing, API-key minting, or operator-management actions.
