Google+ has announced it’s going to shut down 4 months earlier in April 2019 rather than August 2019 due to a security concern that could affect the personal data of over 52 million users.
Google engineers discovered the flaw in their API on the “People – get” endpoint. The issue was that data was available despite whether it had been made public or private. The data includes such fields as names, email addresses, occupations and age.
Google fixed the bug within a week of discovery and claim they have seen no evidence of it been exploited in the wild.
This type of bug would be classified under OWASP
