{"id":"CVE-2026-53546","summary":"Termix: Missing authorization in SSH host credential resolution exposes stored credentials","details":"Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 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.","aliases":["GHSA-57gp-39c7-4g9r"],"modified":"2026-09-11T03:30:57.244858642Z","published":"2026-08-19T20:36:19.279Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53546.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-639","CWE-862"]},"references":[{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/releases/tag/release-2.3.2-tag"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53546.json"},{"type":"ADVISORY","url":"https://github.com/Termix-SSH/Termix/security/advisories/GHSA-57gp-39c7-4g9r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53546"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/commit/52f4e51ae03b5b8d2608e1383e2ccf79d290132b"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/pull/874"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/termix-ssh/termix","events":[{"introduced":"0"},{"fixed":"52f4e51ae03b5b8d2608e1383e2ccf79d290132b"},{"fixed":"c3282b5dca081d52513e94329bbc71084338217d"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.3.2"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["release-2.2.1-tag","release-2.2.0-tag","release-2.1.0-tag","release-2.0.0-tag","release-1.11.2-tag","release-1.11.1-tag","release-1.11.0-tag","release-1.10.0-tag","release-1.9.0-tag","release-1.8.0-tag","release-1.7.3-tag","release-1.7.2-tag","release-1.7.1-tag","release-1.7.0-tag","release-1.6.0-tag","release-1.5.0-tag","release-1.4.0-tag"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-53546.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N"}]}
