{"apiVersion":"1.0","identifier":"CVE-2026-53546","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":"2026-08-19T21:16:56","lastModifiedAt":"2026-08-20T20:17:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53546","cvssScore":9.6,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N","epssProbability":0.00362,"riskScore":0.99,"affectedProduct":"Termix","affectedVersions":"<2.3.2","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53546","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53546","en":"https://www.redsauce.net/en/cves/CVE-2026-53546","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53546","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53546","de":"https://www.redsauce.net/de/cves/CVE-2026-53546","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53546","el":"https://www.redsauce.net/el/cves/CVE-2026-53546"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53546"}}
