Help needed diagnosing light leak

[Arbitrarium]

Hiya, I just got my first roll back with my Super Baldax and almost every frame has a little corner leak. It comes right from the edge of the film, so I would have assumed it wasn't tight enough on the spool when loading/removing, but the leak isn't all the way along the edge, just a little burst pattern at the corners. Can't imagine it's anything to do with shutter or bellows as it starts outside the frame, but a door leak like this makes no sense either... Ideas?

It happened surely inside the camera.

The leak extends beyond the frame mask, so to me it looks like the light's getting into the back of the camera.

Strong enough flashlights are very small these days. Put one in facing the back. Close camera and roll flashlight for every four corners.

Agreed. I put the flashlight in to look from the outside in, then on the outside to look from the inside out. All inside a darkened room.

...and what happened...?
