  "title": "Improper route access control in Mercury standalone mode",
  "summary": "Mercury standalone versions after 3.0 through 3.2.11 expose Jupyter configuration, settings, export, and terminal-related routes outside intended restrictions. An anonymous user of a public-mode server can alter shared configuration or settings and access notebook exports; if an existing terminal is available, they can connect to it and execute commands. Terminal command execution requires anonymous public-mode access and a pre-existing terminal.",
  "mitigation": "Upgrade Mercury to 3.2.12 or later, then restart running servers and replace deployed runtime images. Until upgraded, require authentication and disable terminal access; do not rely only on blocking the terminal REST API.",
