{"id":"CVE-2026-53546","state":"PUBLISHED","title":"Termix: Missing authorization in SSH host credential resolution exposes stored credentials","description":"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.","publishedAt":"2026-08-19T20:36:19.279Z","updatedAt":"2026-08-20T19:36:36.598Z","severity":{"score":9.6,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["Termix-SSH Termix"],"affected":[{"vendor":"Termix-SSH","product":"Termix","versions":[{"version":"< 2.3.2","status":"affected"}]}],"references":["https://github.com/Termix-SSH/Termix/security/advisories/GHSA-57gp-39c7-4g9r","https://github.com/Termix-SSH/Termix/pull/874","https://github.com/Termix-SSH/Termix/commit/52f4e51ae03b5b8d2608e1383e2ccf79d290132b","https://github.com/Termix-SSH/Termix/releases/tag/release-2.3.2-tag"],"weaknesses":["CWE-639","CWE-862"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/53xxx/CVE-2026-53546.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-53546","state":"PUBLISHED","datePublished":"2026-08-19T20:36:19.279Z","dateUpdated":"2026-08-20T19:36:36.598Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-09T18:13:07.263Z"},"containers":{"cna":{"title":"Termix: Missing authorization in SSH host credential resolution exposes stored credentials","descriptions":[{"lang":"en","value":"Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities.
