A security flaw has been discovered in philz1337x clarity-upscaler up to cfbdb842c6c839c8e97741722b8cf9a4b7662d98. This impacts the function create_html_for_item of the file modules/ui_extra_networks.py of the component Extra Networks Card Rendering. The manipulation of the argument Description results in cross site scripting.

The attack can be executed remotely. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. All versions in the repository are affected, as the codebase is based on AUTOMATIC1111/stable-diffusion-webui v1.7.0 code.

Upstream AUTOMATIC1111/stable-diffusion-webui (v1.8.0, released March 1, 2024) contains the fix. The project was informed of the problem early through an issue report but has not responded yet.
