CVE-2026-47723

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.1, none of the response paths in internal/web/ or internal/api/ set the standard browser-security headers. grep for Content-Security-Policy, X-Frame-Options, Strict-Transport-Security,...

CVE-2026-47724

nebula-mesh is a self-hosted control plane for Slack Nebula mesh virtual private network. Prior to version 0.3.4, the /api/v1/ route surface trusts the bearer token alone for authorisation on most endpoints.

CVE-2026-47724

Nebula-Mesh (pre-0.3.4) suffers an authorization gap: the /api/v1/* surface largely trusts bearer tokens and enforces ownership only for the Web layer, leaving host, network, firewall, mobile-bundle, and most operator endpoints vulnerable to cross-tenant access. This enables privilege escalation ...

CVE-2026-47723

Nebula-mesh is affected by missing security headers in internal/web/ and internal/api/ paths prior to v0.3.1 (up to v0.3.0). The root cause is absence of standard headers such as CSP, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Strict-Transport-Security in responses, enabling cl...
