Risk summary
Not in the CISA KEV catalog. EPSS exploit probability 3.5%. CVSS 8.8 (High).
This CVE is among the lower half of tracked Microsoft CVEs by EPSS exploit probability.
This is a client-side Remote Code Execution flaw with Severity Critical (CVSS 9.8) that triggers through the Remote Desktop Client, not the RDP server, so a malicious or compromised RDP host can attack the connecting machine. Exposure covers Windows 11 version 26H1 on ARM64 and x64 plus the Windows App Client for Windows Desktop, which means jump boxes, admin workstations, and roaming users who connect out to untrusted or third-party RDP endpoints. The 64 percent EPSS score signals elevated near-term exploitation likelihood even though it is not yet in CISA KEV or tied to ransomware.
Do this: Patch the Remote Desktop Client and Windows App Client on all Windows 11 26H1 systems now, prioritizing machines that initiate RDP sessions to external or untrusted hosts.
