The flagged text is just the extension's built-in starting address for reaching the user's own image-generation program running on their own computer. Unencrypted web addresses are normal for software on your own machine, and this address points only at the user's own setup, not at any outside service. Nothing is actually sent from this line; it is a default value the user can change.
Technical evidence
Scanner reason: JavaScript analysis matched static JavaScript security signal javascript.xray.shady-link. The match applies to this repository.
Contextual assessment: The scanner's shady-link heuristic flagged a literal plain-HTTP URL inside the extension's default settings object. The literal is a loopback address on the conventional ComfyUI port — the standard default endpoint of a locally running ComfyUI server, which is precisely the backend this extension is documented to drive. The line only defines a user-configurable default value; no network request originates from it, and the destination is the user's own machine rather than any external host. Plain HTTP to loopback is normal for local services, which typically do not terminate TLS. No credentials, chat content, or other data flow through this constant, and the surrounding code is ordinary settings persistence and preset management via SillyTavern's extension-settings API.
