WhatsApp is probably the world's biggest instant messaging service, and despite being owned by Meta, it has some privacy features, such as encryption and "one-time" sending of videos, photos, and voice notes. Someone might have just found a fatal flaw with the latter feature.
A significant security flaw has been discovered in WhatsApp's "View Once" feature on its
web app. This vulnerability allows malicious actors to save images and videos meant to disappear after being viewed, undermining the privacy intentions of the feature.
