Description
A vulnerability has been found in AUTOMATIC1111 stable-diffusion-webui up to 1.10.1. This affects the function create_item_html of the file modules/ui_extra_networks.py of the component Card Builder. The manipulation of the argument filename leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
A cross-site scripting (XSS) vulnerability has been identified in AUTOMATIC1111 stable-diffusion-webui versions through 1.10.1. The issue arises in the Card Builder component, specifically within the create_item_html function of modules/ui_extra_networks.py. The vulnerability is triggered by the unescaped interpolation of filenames into the HTML of extra-networks cards. This flaw allows for the execution of injected scripts in the context of the WebUI's origin, as the crafted filename is processed without proper sanitization. The vulnerability can be exploited remotely, and has been publicly disclosed.
Users can manually escape filenames before uploading them to the models directory, or wait for an official patch that addresses the HTML injection issue.
