Cyber firm Wiz says flaw could have led to mass exposure of Microsoft cloud customers

Reuters reports that Wiz uncovered a serious but now-patched vulnerability in Microsoft’s Azure CosmosDB database service that could have allowed hackers to remotely compromise users, potentially exposing Microsoft cloud customers and sensitive data. Microsoft said the issue was fully addressed with Wiz and that it found no evidence of customer impact. The story is negative from a cybersecurity-risk perspective but appears limited in immediate market damage because the flaw was patched before exploitation was observed. Still, it highlights recurring cloud-security risks for Microsoft’s Azure platform and could weigh on sentiment around enterprise cloud and database security services. Alphabet-owned Wiz’s disclosure also underscores continued scrutiny of major cloud providers and the potential for reputational risk if similar flaws emerge again.
