    "summary": "## Summary Incomplete fix of GHSA-5v7c-xpfp-p65m: the secure-session (OTP step-up) requirement added to the nginx, cert, dns, backup, site, and stream mutation routers was not applied to the parallel api/cluster router, so cluster node management and cluster-wide nginx reload/restart run with only a JWT and no step-up. An authenticated user whose JWT is stolen or persisted, but who does not hold a fresh secure-session, can perform cluster node CRUD (including reading and rewriting a node token secret) and trigger cluster-wide nginx reload/restart. Confirmed at HEAD 2cb7ee9102c9d87274de2fa104db804841d140a0. ## The defect GHSA-5v7c-xpfp-p65m required a fresh secure session (an OTP step-up beyond the JWT) for sensitive mutation routes. The fix wrapped the nginx, cert, dns, backup, site, and stream mutation handlers in middleware.RequireSecureSession() and added reload/restart to the MCP sensitive-tool list. It did not touch the physically separate api/cluster package, whose router registers the same class of sensitive operations on the bare authenticated group. The fixed sibling, api/nginx/router.go: ```go o := r.Group(\"\", middleware.RequireSecureSession()) // line 28 { o.POST(\"nginx/reload\", Reload) // line 30 o.POST(\"nginx/restart\", Restart) // line 31 } ``` The missed router, api/cluster/router.go, registers every sensitive operation directly on r with no RequireSecureSession wrapper: ```go nodeGroup := r.Group(\"nodes\") // line 9, no step-up { nodeGroup.POST(\"\", AddNode) // l",
