EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.9%, top 44% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
