Bulk image rotation

Yes, this is a known problem between ios devices and WordPress. It’s a real issue due to the high numbers of iPhone/ipad users who also use WordPress, and I’m surprised it hasn’t been addressed in the WordPress core. Looks like it’s still being debated/ worked on here.

It’s a question that’s been asked before here. As that answer notes, there are plugins for this job, including ios images fixer and image rotation repair (not updated for a while) and Image Rotation Fixer although I’m not sure if they apply to existing images or only new uploads.
