Summary
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.
