Microsoft Fixes vulnerability found in Azure called Autowarp

A benefit of working with the community, Microsoft quickly patched a vulnerability found in Azure by a researcher from Orca.

The vulnerability is explained in details by the company, Orca and its researcher. A summary is highlighted by venturebeat.com, which I quote:

If it had not been caught and fixed, the critical vulnerability could have allowed someone to cross from one tenant within Azure to another tenant — potentially allowing them to access data and resources from numerous other customers, according to Orca Security.
