You made the mistake of bringing up that scar of hers, which is still a bit of a hot topic.

We haven't really seen anything regarding Weiss's actions that would lead to that conclusion. Yang or Nora maybe, for the incredible strength they show, or possibly Ren for his aceptional aura control (though I think that's simply great skill), but not Weiss. Probably not Blake, Ruby or Pyrrha either, they also haven't shown anything that couldn't be explained by great skill. Cinder maybe, or her actions could be explained by semblance or dust clothing.

We don't really have anything to base any speculation on other then that one vague line. The clothing aspect is a lot easier since enchanted clothing has been around in fantasy practically forever, but direct magic to body application is considerably rarer, though it is out there.
