Ster-Kinekor had a vulnerability in their site/api that allowed anyone to get the profile details of every single user in their system. Those details included names, addresses, phone numbers, and plain text passwords (amongst a draw of other fields that you canful insure below).
To be clear, this wasnt a hard thing to encounter at all, and from Ster-Kinekors side, it was just pure negligence. Not only did the API hand off details to anyone, they were also storing password in their database in plaintext (and returning those to the client!).
