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.

WhatsApp Web photo privacy bug

According to Indrajeet Bhuyan , 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.

WhatsApp Web Photo Sync Bug

The second security hole points out the WhatsApp Web Photo Syncing functionality. Indrajeet Bhuyan noticed that whenever a user deletes a photo that was sent via the mobile version of WhatsApp application, the photo appears blurred and can’t be viewed.
However, the same photo, which has already been deleted by the user from mobile WhatsApp version, can be accessible by Whatsapp Web as the photo does not get deleted from its web client, revealing the fact that mobile and web clients of the service are not synced properly.
