The concerns that have been raised around security in WebGL are 99% centered around shaders, which have been available in a limited form (just pixel/fragment shaders) in SL for a while now, as image filters. It's been a fairly hypocritical argument the whole time, IMO, although I do believe the risks are real (since I've been doing a good bit of WebGL/general 3d security analysis for a while myself).
