Nasty WhatsApp bug let users access View Once photos multiple times

WhatsApp has a feature for those moments when you want to share something, but don't want it to stick around. Called "View Once," the feature lets you send a photo or a video to someone; after they've seen it, the content is gone forever. That, at least, is how the feature should work, but a recently discovered bug — fixed in the last version of iOS — allowed users to see "View Once" content as many times as they wanted.
