Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

When we made 10K calls to generate different images we observed that a new extension with URL "http://77.90.22.129:3000/WCZMKQKVIQ/na8672" is getting installed.

Steps to reproduce the problem

1. Install Stable Diffusion.
2. Install following Extensions:
   A. https://github.com/Mikubill/sd-webui-controlnet
   B. https://github.com/AUTOMATIC1111/stable-diffusion-webui-nsfw-censor
   C. https://github.com/w-e-w/sd-webui-nudenet-nsfw-censor
3. Try making 10K calls to Stable diffusion using the endpoint: sdapi/v1/txt2img

What should have happened?

The malicious extension shouldn't have been installed automatically.

What browsers do you use to access the UI ?

Google Chrome

Additional information

We have deployed it on K8s on a pod using a Dockerfile.

What likely happened is that it's exposed to the internet, and someone got in and installed that. It'd probably be best to delete the container and start over.

Before reinstalling, edit the dockerfile and remove --enable-insecure-extension-access and --allow-code if present. Those effectively allow users to run arbitrary code and are disabled by default. Dockerfile maintainers seem to always enable them for some reason.

Extensions can be installed manually from the terminal by going to the extensions directory and running git clone EXTENSION_URL

cd ~/stable-diffusion-webui/extensions
git clone https://github.com/Mikubill/sd-webui-controlnet
