{"schema":"threatline.record/2","record":{"id":"CVE-2026-93994","aliases":[],"summary":"Apache MINA SSHD: Repeated-publickey policy bypass on server","details":"Apache MINA SSHD is a Java library for client-side and server-side SSH. SSH servers can be configured to require multi-authentication schemes, for instance two different public keys, not just one. In OpenSSH, this would be done by setting in sshd_config AuthenticationMethods \"publickey,publickey\". Apache MINA SSHD provides an equivalent configuration mechanism.\n\n\n\n\nIn Apache MINA SSHD versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5 the server code in component sshd-core does not enforce that the two public keys presented are different. A user can thus successfully authenticate with only one of the two key pairs required by presenting this single key twice. This is a partial authentication bypass.\n\n\n\n\n\n\nUsers are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.","categories":["Unclassified"],"product":"Apache MINA SSHD","vendor":"Apache Software Foundation","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93994","source_modified_at":"2026-09-30T14:29:38.124Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Apache MINA SSHD","vendor":"Apache Software Foundation","versions":[{"status":"affected","version":"0","lessThan":"2.20.0","versionType":"maven"},{"status":"affected","version":"3.0.0-M1","lessThan":"3.0.0-M6","versionType":"maven"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93994","source_modified_at":"2026-09-30T14:29:38.124Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache MINA SSHD","ecosystem":null},"version":"2.20.0","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93994","source_modified_at":"2026-09-30T14:29:38.124Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Apache MINA SSHD","ecosystem":null},"version":"3.0.0-M6","basis":"first unaffected version stated in the CVE record"}],"cvss":8.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00315,"percentile":0.23188,"score_date":"2026-10-23"},"published_at":"2026-09-30T09:45:32.561Z","modified_at":"2026-09-30T14:29:38.124Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93994","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T14:29:38.124Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93994","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://lists.apache.org/thread.html/9t3vsm8rnvwdv9779mlg1lq2fbwojdwp","tags":["vendor-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-09-30T14:29:28.530614Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T14:29:38.124Z","content_hash":"ab86cf12f5d72ff4ebe00a49413675fbf9d03f5a1ea954810cc8afe4d314f798"}}
