What makes you think it comes from the lens?

These look like holes in a shutter curtain

There are similarities in the distribution of bright spots between the two images, which suggests a common set, like pinholes in the shutter curtain as Hunter_Compton suggested.

The bright pentagonal spots in the second image are images of the lens aperture, not reflections off it. This more commonly happens when you get flare from out of focus highlights or light sources, like the sun in/near the frame causing internal reflections in the lens and an out of focus ghost image. The slightly odd thing is that pinholes in the shutter curtain are typically close to in-focus, because the curtain is so close to the film and far from the lens. However, the Jupiter 35mm has a very large rear element that is very close to the shutter curtain, so maybe it can illuminate the pinholes in a way that casts the holes out of focus onto the film. Anyway, it should be easy to test for pinholes with a flashlight. You have to test in both the unwound and wound states.
