Technical details
The vulnerability is a command injection flaw in src/backend/database/routes/acme-ssl-routes.ts where user-controlled domain and email values from PATCH /users/acme-ssl-settings are passed to child_process.execSync invoked with /bin/sh -c and wrapped only in double quotes, allowing shell metacharacter injection. An authenticated administrator can trigger arbitrary command execution via POST /users/acme-ssl-request, affecting both HTTP webroot and DNS Cloudflare challenge modes. The fix replaces execSync with execFileSync to prevent shell interpretation.
