## 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.P
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. FIRST EPSS
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
