Improper input validation in Microsoft Office SharePoint allows an unauthorized attacker to execute code locally.

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges.

Deserialization of untrusted data in Microsoft Office SharePoint allows an authorized attacker to execute code over a network.

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment of the targeted component.

Heap-based buffer overflow in Windows Media allows an unauthorized attacker to execute code locally.

**Are there additional steps I need to take to be protected from this vulnerability?** Admins should take the following steps to be protected from CVE-2026-0386: 1. Audit existing WDS usage and identify hands-free deployments. 2. Opt in for protection by configuring the registry settings described in: Windows Deployment Services (WDS) Hands-Free Deployment Hardening Guidance. This will provide immediate protection. This security protection will be enabled by default in a future security update release and no additional administrator action will be required. **How is Microsoft addressing this vulnerability?** To address this vulnerability, by default the hands-free deployment feature will not be supported beginning with a security update in a future release in mid-2026. **Why is the WDS Unattended Installation feature being deprecated?** The legacy WDS workflow transmits unattend.xml over unauthenticated RPC, exposing sensitive credentials during PXE boot. This creates a securi...
