CVE-2026-53548

A failed requester-scoped lookup can resolve the host with the owner's context and return the owner's plaintext credential, allowing any authenticated user with a valid JWT to enumerate sequential hosts.id values and retrieve SSH or sudo passwords…

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.46%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.6.1, the GET /host/db/host/:id/password endpoint in src/backend/database/routes/host.ts accepts an authenticated user's numeric host ID and the field=password or field=sudoPassword query without enforcing host ownership during credential resolution. A failed requester-scoped lookup can resolve the host with the owner's context and return the owner's plaintext credential, allowing any authenticated user with a valid JWT to enumerate sequential hosts.id values and retrieve SSH or sudo passwords belonging to other users. The disclosed credentials can then be used to access and control managed systems outside the Termix instance. This issue is fixed in version 2.6.1.
