Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.8.0 until 2.5.1, authenticated Termix users can access the server-stats API without per-host authorization. GET /status returns statuses for hosts the requester cannot access, GET /status/:id accepts an attacker-supplied numeric host identifier, and POST /clear-connections permits a regular user to clear the global SSH connection pool. The affected src/backend/ssh/server-stats.ts routes expose host online or offline state and lastChecked timestamps and can disrupt other users' active sessions or pooled connections. Unauthenticated requests remain blocked, but authentication alone does not preserve tenant isolation. This issue is fixed in version 2.5.1.

EG Risk 40/100

EG Risk is EchelonGraph's 0–100 priority score. It fuses impact severity (EG Severity, the CVSS base score, never the KEV-floored or EPSS-lifted EG Score) with real-world exploitation and automatability, under weights EchelonGraph set by hand, so you can rank equal-severity CVEs and fix the most dangerous first. Higher = act sooner.

Exploitation public PoC (CISA Vulnrichment) · Automatable no (CISA Vulnrichment) · Technical impact partial (CISA Vulnrichment). All three are CISA's SSVC values (Vulnrichment). EchelonGraph applied CISA's decision table to them; CISA publishes SSVC inputs and the table, not a decision for each CVE. Mission impact is CISA's Mission & Well-being decision point, and only you can judge it. CISA's table makes it high when Mission Prevalence is Essential — the vulnerable component "directly provides capabilities that constitute at least one MEF for at least one entity" (MEF: mission essential function) — or when Public Well-Being Impact is Irreversible: "multiple fatalities are likely", the cyber-physical system "is likely lost or destroyed", "extreme or serious externalities" are imposed on other parties, or social systems such as elections or the financial grid "are destabilized and potentially collapse".
