This high-severity CVE scores 8.1 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% 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).

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 16 file-manager endpoints in Termix prior to version 2.3.2 do not verify that the requesting user owns the SSH session identified by sessionId. An authenticated attacker who knows or guesses another user's active sessionId can read, write, delete, download, and execute files on the victim's connected SSH host. Version 2.3.2 patches the issue.
