This is just a default address for connecting to the user's own local image-generation software. It is exactly what the extension is supposed to do and poses no security concern.
Technical evidence
Scanner reason: JavaScript analysis matched static JavaScript security signal javascript.xray.shady-link. The match applies to this repository.
Contextual assessment: The flagged link is a default localhost URL (127.0.0.1:8188) for a local ComfyUI instance, matching the project's stated purpose of connecting to a user's local ComfyUI. It is a plain default configuration value with no exfiltration, obfuscation, or external destination.
The link the scanner noticed is just the default address for the user's own local image-generation program, which is what this extension is built to talk to.
Technical assessment
The scanner signal corresponds to the default comfyUrl value pointing to localhost:8188, the standard ComfyUI port. This is an inline default in the DEFAULTS object, consistent with the README requirement that ComfyUI be reachable from the SillyTavern host. No untrusted input flows to this value and no external destination is involved.
