CVE-2026-50523: Microsoft PowerShell Remote Code Execution Vulnerability
Noroxi assessment
Priority: Monitor (action score 31/100)
- The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
- Probability of exploitation in the next 30 days: 0.32% (FIRST EPSS).
- Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: PowerShell 7.4 7.4.19.0; PowerShell 7.5 7.5.10.0; PowerShell 7.6 7.6.5.
Low priority for now. Upgrade to PowerShell 7.4 7.4.19.0; PowerShell 7.5 7.5.10.0; PowerShell 7.6 7.6.5 or later.
