Windows 10 Version 1607: Exposure of Sensitive System Information to an Unauthorized Control Sphere

Published Updated By the CyberSecBulletin desk

CVE-2026-119822 is a high-severity exposure of sensitive system information to an unauthorized control sphere vulnerability in Windows 10 Version 1607 from Microsoft, with a CVSS 3.1 base score of 7.0 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 10.0.14393.9688 as the first without the flaw, so updating Windows 10 Version 1607 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

Official description

Exposure of sensitive system information to an unauthorized control sphere in Windows Overlay Filter allows an authorized attacker to elevate privileges locally.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Exposure of Sensitive System Information to an Unauthorized Control Sphere

The product does not properly prevent sensitive system-level information from being accessed by unauthorized actors who do not have the same level of access to the underlying system as the product does.

How developers prevent this class of flaw

  • Production applications should never use methods that generate internal details such as stack traces and error messages unless that information is directly committed to a log that is not viewable by the end user. All error message text should be HTML entity encoded before being written to the log file to protect against potential cross-site scripting attacks against the viewer of the logs
