CVE-2026-50661

BitLocker is Windows’ built-in way to protect your data on a disk by encrypting it. This issue is a weakness where someone who can get hands-on with the device can bypass BitLocker’s protection without needing a password or user actions, which means the stored data may be easier to access.

This matters if you use or manage Windows 10, Windows 11, or Windows Server 2016/2019/2022/2025 systems with BitLocker-enabled drives. The risk is specifically for situations where an attacker can get physical access to the device (for example, an unattended laptop or a server you can’t fully control). There’s no login needed and no clicks required, so treat physical access as the gate: it’s a risk when the device is reachable in person by an attacker.

Verdict is RED because this is a security-feature bypass that works with physical access and requires no authentication or user interaction. Even though public exploit details and KEV listing aren’t provided here, the practical scenario (someone having hands-on access) can be real for small businesses, making fast patching important.
