Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-48804 is a vulnerability found in Windows BitLocker that enables an unauthorized attacker to bypass a security feature through a physical attack. This bypass occurs due to the system's acceptance of extraneous untrusted data alongside trusted data. More specifically, this vulnerability can be exploited by leveraging Windows Recovery Environment (WinRE) app trust validation. An attacker can utilize the pre-registered `SetupPlatform.exe` to gain persistent command-line access through keyboard shortcuts, thereby circumventing BitLocker's protections.
