Summary
A vulnerability has been found in AUTOMATIC1111 stable-diffusion-webui up to 1.10.1. It affects create_item_html in modules/ui_extra_networks.py of the Card Builder component. Manipulating the filename argument leads to cross site scripting, the attack can be initiated remotely, and the exploit has been disclosed publicly. The project was informed but has not responded yet.
Risk Assessment
A remote attacker can inject malicious script executed in the user's browser, potentially leading to session or credential theft.
Recommendation
Restrict access to the stable-diffusion-webui interface to trusted networks and avoid opening untrusted filenames; track project updates for a fix.

- CVE-2026-82288High
Stable Diffusion WebUI through 1.10.1 contains a credential disclosure vulnerability in the /sdapi/v1/cmd-flags endpoint that returns parsed command-line arguments including gradio_auth and api_auth values in cleartext. Unauthenticated attackers can access this endpoint to retrieve configured usernames and passwords, then use them to authenticate to the interface and access the application.
- CVE-2026-77815High
to_abs_path in scripts/iib/tool.py normalizes the path with os.path.normpath, which does not resolve symbolic links. A symlink placed inside a scanned directory can point outside that directory, and FileResponse follows the link, disclosing files such as /etc/passwd.
- CVE-2026-77814High
is_path_trusted in scripts/iib/api.py compares the requested path against allowed parent directories with path.startswith(parent_path), without appending a path separator. A directory whose name merely begins with an allowed path satisfies the comparison, allowing access to files outside the allowed directory.
