Prior to 2.3.2, the terminal WebSocket accepts a user-controlled hostConfig.id and src/backend/ssh/host-resolver.ts resolves that host without requiring ownership or explicit access. When no credential is shared with the requester, resolveHostById performs an owner credential fallback, and src/backend/ssh/terminal.ts combines that credential with attacker-controlled ip, port, and username values. An authenticated low-privileged user can therefore make Termix authenticate to an attacker-controlled SSH server and disclose another user's stored SSH password or private-key material while the victim user's data key is unlocked. This issue is fixed in version 2.3.2."}], "lastModified": "2026-09-09T21:15:59.613", "sourceIdentifier": "security-advisories@github.com"}
