CVE-2026-6847: 4real Themisnetpanel

Critical severity, CVSS 9.3. EPSS: 0.9% chance of exploitation in the next 30 days.

Remote Code Execution vulnerability exists in ThemisNETPanel due to missing authentication for a critical file upload function. The application exposes an endpoint that allows unauthenticated attackers to upload arbitrary PHP files by providing a base64-encoded payload and to execute arbitrary code on the underlying server. This issue has been fixed by a patch released in April 2026.
