CVE-2023-0400

Status: ModifiedHigh (8.2)—

The protection bypass vulnerability in DLP for Windows 11.9.x is addressed in version 11.10.0. This allowed a local user to bypass DLP controls when uploading sensitive data from a mapped drive into a web email client. Loading from a local driver was correctly prevented. Versions prior to 11.9 correctly detected and blocked the attempted upload of sensitive data.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
