CVE-2026-13800 is a high-severity local privilege escalation vulnerability in the Updater component of Google Chrome on Windows platforms before version 150.0.7871.47.

The vulnerability impacts confidentiality, integrity, and availability at a high level (CVSS 7.8). The vendor has published an advisory but has not explicitly stated the remediation level or patch availability in the provided data. No known exploits have been reported in the wild.

Successful exploitation of this vulnerability enables a local attacker to gain elevated operating system privileges, potentially allowing full control over the affected system. This can lead to unauthorized access to sensitive data, system modification, and disruption of services.
