Affected platforms span Windows 10 (multiple versions), Windows 11, and Windows Server 2012 through 2025 as confirmed by EUVD version data and Microsoft CPE strings. No public exploit has been identified at time of analysis, EPSS is extremely low at 0.21% (11th percentile), and CISA SSVC classifies this as no active exploitation with non-automatable attack paths, positioning this as a low-urgency but meaningful local disclosure risk.
Windows Media on multiple Windows client and server editions exposes sensitive information to authenticated local users, classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). Affected builds span Windows 10 1809 through Windows 11 26H1 and Windows Server 2019 through 2025, representing a broad footprint of Microsoft's supported OS ecosystem. No active exploitation has been identified at time of analysis - the vulnerability is absent from CISA KEV, EPSS sits at 0.36% (28th percentile), and SSVC assesses exploitation status as none - making this a patch-and-monitor priority rather than an emergency response.
BitLocker's protection mechanism on Windows fails to enforce a critical authentication or verification step, permitting a physically present attacker to bypass full-disk encryption without credentials, a recovery key, or elevated privileges. Despite a CVSS score of 6.8 (Medium) - moderated by the physical access requirement - the impact ratings are High across confidentiality, integrity, and availability, meaning successful exploitation grants complete access to encrypted data and the underlying system. No public exploit has been identified at time of analysis, and Microsoft has released a patch via the MSRC update guide.
Security feature bypass in Microsoft Windows BitLocker allows an attacker with physical access to circumvent the drive encryption protection mechanism. Affected systems can have BitLocker-protected data accessed despite the encryption-at-rest control being enabled, undermining a core platform confidentiality boundary. There is no public exploit identified at time of analysis, but the vulnerability is reported by Microsoft (secure@microsoft.com) as a protection mechanism failure with high impact across confidentiality, integrity, and availability.
BitLocker drive encryption on Windows can be bypassed by a physically present, unauthenticated attacker, exposing protected volume contents with high confidentiality impact. Classified as CWE-693 (Protection Mechanism Failure), the flaw undermines BitLocker's core threat model - data-at-rest protection - across a wide range of Windows 10, Windows 11, and Windows Server releases from 2012 through 2025. No public exploit has been identified at time of analysis, and Microsoft has released patches for all affected versions; however, the physical access requirement means organizations with mobile or physically accessible systems should treat this as a higher operational priority than the CVSS score alone implies.
Spoofing via improper input validation affects Microsoft Azure Attestation service and the Device Health Attestation Service component across a broad range of Windows OS versions, from Windows Server 2012 through Windows Server 2025 and Windows 10/11. An authorized attacker with high privileges and physical access to the target device can manipulate attestation inputs to spoof device health or platform integrity status, achieving a high-integrity impact with no confidentiality or availability consequence. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog; the CVSS score of 3.9 (Low) reflects the significant physical and privilege barriers to exploitation.
Out-of-bounds read in the Windows DHCP Server service enables a locally authenticated, low-privileged attacker to disclose contents of process memory on affected systems. The CVSS vector (AV:L/AC:L/PR:L/UI:N) confirms this is a local, low-complexity attack requiring only standard user privileges - no elevated rights or user interaction needed. Exploitation is constrained to hosts where the Windows DHCP Server role is actively installed and running, which significantly limits the attack surface to designated infrastructure servers rather than general workstations. No public exploit code has been identified at time of analysis, and this CVE does not appear in the CISA KEV catalog.
