Microsoft Corp.’s AI research team accidentally exposed a large cache of private data on the software development platform GitHub, according to new research from a cybersecurity firm.

A team at the cloud security company Wiz found the exposure of cloud-hosted data on the AI training platform via a misconfigured link. The data was leaked by Microsoft’s research team while publishing open-source training data on GitHub, according to Wiz.
