Why is my texture glowing without emission node?

[NODARman]

I made a simple wave texture and after some changes, I’ve found this weird bug or my fault, IDK.

In this scene, there is no light source, only this object.

With a light source, it shows well, but after I disable the lamp and world emission, it glows in dark.

You plugged color (yellow link) directly into shader socket (green). Put Diffuse BSDF shader node in between.
I believe this should solve your problem.
