Last week, the most popular mobile messaging application WhatsApp finally arrived on the web — dubbedWhatsApp Web, but unfortunately it needs some improvements in its web version.
An independent 17-year-old security researcher Indrajeet Bhuyan reported two security holes in the WhatsApp web client that in some way exposes its users’ privacy. Bhuyan called the first hole, WhatsApp photo privacy bug and the other WhatsApp Web Photo Sync Bug.
Bhuyan is the same security researcher who reported us the vulnerability in the widely popular mobile messaging app which allowed anyone to remotely crash WhatsApp by sending a specially crafted message of just 2kb in size, resulting in the loss of conversations.
Whatsapp Photo Privacy Bug
According to him, the new version of WhatsApp Web allows us to view a user’s profile image even if we are not on the contact list of that user. Even if the user has set the profile image privacy setting to "Contacts Only," the profile picture can be viewed by out of contacts people as well.
