CVE-2026-53548Network attack vector

Credential disclosure via unchecked host ownership

Published Aug 19, 2026 · Updated Aug 19, 2026

Missing authorization in Termix before 2.6.1 allows remote authenticated users to read other users' stored SSH or sudo passwords. The GET /host/db/host/:id/password route in src/backend/database/routes/host.ts trusts a user-supplied host ID and, after a requester-scoped lookup fails, falls back to the owner's context and returns the owner's plaintext credential. Any account with a valid JWT can enumerate sequential host IDs; disclosed SSH or sudo passwords can then be used to access managed systems outside the Termix instance.
