Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 until 2.5.1, the POST /credentials/:id/deploy-to-host endpoint resolves credential and target-host records from attacker-controlled credentialId and targetHostId integer values without checking that either record belongs to the requesting user. In src/backend/database/routes/credentials.ts, differential errors reveal whether credential and host records exist and disclose each record's authType value. Properly encrypted passwords and keys are not disclosed, but a key-authenticated victim host can receive an outbound SSH connection attempt using the attacker's public key. This issue is fixed in version 2.5.1.
CVE-2026-79759
MEDIUMPre-NVD 4.34.3
EchelonGraph scoreLOW confidence
This medium-severity CVE scores 4.3 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). 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).
