{"id":"CVE-2026-79759","summary":"Termix: Cross-User Information Disclosure via Missing Ownership Check in deploy-to-host Endpoint","details":"Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. From 1.7.0 until 2.5.1, the POST /credentials/:id/deploy-to-host endpoint resolves credential and target-host records from attacker-controlled credentialId and targetHostId integer values without checking that either record belongs to the requesting user. In src/backend/database/routes/credentials.ts, differential errors reveal whether credential and host records exist and disclose each record's authType value. Properly encrypted passwords and keys are not disclosed, but a key-authenticated victim host can receive an outbound SSH connection attempt using the attacker's public key. This issue is fixed in version 2.5.1.","aliases":["GHSA-w4cf-69fj-g96f"],"modified":"2026-09-27T03:30:17.967699082Z","published":"2026-09-24T15:59:43.119Z","database_specific":{"cwe_ids":["CWE-639"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79759.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/Termix-SSH/Termix/releases/tag/release-2.5.1-tag"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/79xxx/CVE-2026-79759.json"},{"type":"ADVISORY","url":"https://github.com/Termix-SSH/Termix/security/advisories/GHSA-w4cf-69fj-g96f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-79759"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/commit/b0598294a6aeed866f51ce58067f43c1d751c7a6"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/commit/ddbdd5c437c2296607dfaa4265d6f63fbc1ca92e"},{"type":"FIX","url":"https://github.com/Termix-SSH/Termix/pull/1067"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/termix-ssh/termix","events":[{"introduced":"a7fa40393d14dbb8ff1cc3b9d29fd7c014efc45a"},{"fixed":"b0598294a6aeed866f51ce58067f43c1d751c7a6"},{"fixed":"ddbdd5c437c2296607dfaa4265d6f63fbc1ca92e"}],"database_specific":{"extracted_events":[{"introduced":"1.7.0"},{"fixed":"2.5.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["release-2.5.0-tag","release-2.4.1-tag","release-2.4.0-tag","release-2.3.2-tag","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"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-79759.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
