EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 67% 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. Prior to 2.3.2, the POST /database/export endpoint creates a user export that includes the global settings table even though the rest of the export is user-scoped. The settings table contains reset_code_ and temp_reset_token_ password-reset artifacts, allowing a low-privileged authenticated user to recover another local account's reset code and complete the normal password-reset flow. Successful exploitation results in local-user account takeover and administrative compromise when the victim is an administrator. This issue is fixed in version 2.3.2.
