CVE-2026-79759: Termix credential access control bypass in deployment endpoint

CVE-2026-79759 · Severity: medium · CVSS 4.3 · Published 2026-09-24

Termix is a web-based SSH terminal and server management platform. An unauthenticated attacker can access other users' stored SSH credentials and deploy them to arbitrary hosts by exploiting an access control flaw in the credential deployment endpoint. This allows an attacker to launch unauthorized SSH connections to victims' target systems using their own keys, potentially gaining foothold access to critical infrastructure.

Technical details

The POST /credentials/:id/deploy-to-host endpoint fails to validate that credential and target-host records belong to the requesting user, accepting arbitrary integer IDs. Differential error responses disclose the existence and authentication type (password or key) of each record. While encrypted passwords and keys are not directly exposed, an attacker can trigger SSH key deployment to target hosts, enabling SSH connection attempts using the attacker's public key on any key-authenticated system.
