Vulnerability from github – Published: 2026-10-13 03:30 – Updated: 2026-10-13 03:30

Details

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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
