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.","published":"2026-08-19T21:16:56.697","modified":"2026-08-19T21:16:56.697","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/Termix-SSH/Termix/commit/52f4e51ae03b5b8d2608e1383e2ccf79d290132b","label":"Termix-SSH/Termix@52f4e51"},"references":[{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/commit/52f4e51ae03b5b8d2608e1383e2ccf79d290132b"},{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/pull/874"},{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/releases/tag/release-2.3.2-tag"},{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/security/advisories/GHSA-57gp-39c7-4g9r"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T21:16:56.697"}}
