CVE-2026-50369 is a Windows Remote Desktop Services elevation of privilege vulnerability caused by a use-after-free condition. Microsoft rates it High with a CVSS v3.1 base score of 8.8 and temporal score of 7.7. The vector is NETWORK, LOW attack complexity, LOW privileges required, and NO user interaction, with HIGH impacts to confidentiality, integrity, and availability. Microsoft says exploitation is not publicly disclosed, not known to be exploited, and exploit code maturity is UNPROVEN. Because it affects remote desktop services and requires only a network connection plus low privileges, it is relevant for enterprise environments exposed to remote access services.

Highlights:
- CVSS scores: Base 8.8 - Temporal 7.7
- Exploit status & code maturity: Publicly Disclosed: No; Exploited: No; Exploit Code Maturity: UNPROVEN.
- Impact: Elevation of Privilege; confidentiality, integrity, and availability impacts are HIGH.
- Exploitation likelihood: Not stated as “Exploitation More Likely”; Microsoft lists exploitation less likely. Vector context is NETWORK, LOW attack complexity, LOW privileges required, and NO user interaction.
- Severity for enterprise: High. Network-reachable Remote Desktop Services with low-privilege access increase enterprise exposure, especially where RDP or related services are broadly accessible.
- Patch status: available
