This change leverages ComfyUI's new System User Protection API (PR #10966) to provide enhanced security isolation.\n\nThis guide explains what happens during the migration and how to handle various situations.\n\n---\n\n## What Changed\n\n### Finding Your Paths\n\nWhen ComfyUI starts, it displays the full paths in the terminal:\n\n```\n** User directory: /path/to/ComfyUI/user\n** ComfyUI-Manager config path: /path/to/ComfyUI/user/__manager/config.ini\n```\n\nLook for these lines in your startup log to find the exact location on your system. In this guide, paths are shown relative to the `user` directory.\n\n### Path Migration\n\n| Data | Legacy Path | New Path |\n|------|-------------|----------|\n| Configuration | `user/default/ComfyUI-Manager/` | `user/__manager/` |\n| Snapshots | `user/default/ComfyUI-Manager/snapshots/` | `user/__manager/snapshots/` |\n\n##… [truncated]

FAQ: CVE-2025-67303

How does the CVE-2025-67303 exposure work?

Because the configuration/critical-data files sit under a web-accessible path, a remote party who can reach the ComfyUI web interface can read - and, per the advisory, potentially manipulate or overwrite - those files via ordinary HTTP requests, without any dedicated authentication protecting that path.

Which ComfyUI-Manager versions are affected by CVE-2025-67303, and where is it fixed?

Affects ComfyUI-Manager < 3.38; fixed in 3.38.

How severe is CVE-2025-67303?

High severity.

How can I reproduce CVE-2025-67303?

Download the verified script and run it in an isolated environment against ComfyUI-Manager < 3.38; it requests the web-exposed configuration/critical-data path over HTTP from the ComfyUI web interface and confirms the file's contents are retrievable without authentication, then confirms the path is no longer exposed on 3.38.
