CVE-2026-105529 · Severity: high · CVSS 7 · Published 2026-11-10

Windows Storage, which manages data storage on Windows systems, contains a weak authentication mechanism that allows an authorized user on the system to escalate their privileges to a higher level. An attacker with legitimate access to a Windows machine could exploit this flaw to gain administrator-level control, potentially leading to full system compromise and access to sensitive data.
