CVE-2026-50474 is a Windows Remote Desktop Client use-after-free vulnerability that can lead to remote code execution. Microsoft lists the impact as Remote Code Execution with CVSS v3.1 base score 8.8 (High) and temporal score 7.7. The vector is network-based, attack complexity is low, privileges required are none, but user interaction is required. Microsoft reports no public disclosure and no exploitation, with exploit code maturity unproven. Because exploitation requires user interaction, the enterprise risk is higher for environments where users may open or connect to untrusted remote desktop content, but it is not a no-interaction network worm-style issue.

Highlights:
- CVSS scores: Base 8.8 - Temporal 7.7
- Exploit status & code maturity: Publicly Disclosed: No; Exploited: No; Exploit Code Maturity: UNPROVEN.
- Impact: Remote Code Execution with HIGH confidentiality, integrity, and availability impacts.
- Exploitation likelihood: Exploitation Unlikely; the vector is NETWORK with LOW attack complexity, NO privileges required, and USER INTERACTION required.
- Severity for enterprise: High severity from a CVSS standpoint, but real-world risk is moderated by the required user interaction; affected remote desktop client usage remains the main exposure.
