  1. Apply the vendor's update or mitigation from the references below. If there is none yet, limit exposure of the affected service until there is.
  2. If a vulnerable version was live, check your logs and rotate the secrets that server could read.

The advisory

SparkyFitness is a self-hosted, AI-powered health and fitness tracker for families. Prior to 1.6.0, the api/admin/backup/restore endpoint interpolates an uploaded filename into a shell command. An authenticated global administrator uploads a restore archive with a crafted filename. The administrator can supply a restore archive with a filename containing shell metacharacters. Successful exploitation can execute arbitrary operating-system commands with the server process privileges. This issue is fixed in version 1.6.0.

Check your whole app

Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
