In versions prior to OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25), Erlang/OTP SSH fails to enforce strict KEX handshake hardening measures by allowing optional messages to be exchanged. This allows a Man-in-the-Middle attacker to inject these messages in a connection during the handshake. This issue has been patched in versions OTP-27.3.4 (for OTP-27), OTP-26.2.5.12 (for OTP-26), and OTP-25.3.2.21 (for OTP-25).","published_at":"2025-05-08T19:26:27.563000Z","last_modified_at":null,"cvss_v3_score":3.7,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N","cvss_v3_severity":"LOW","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-440"],"nvd_references":["https://github.com/erlang/otp/security/advisories/GHSA-934x-xq38-hhqf","https://github.com/erlang/otp/commit/e4b56a9f4a511aa9990dd86c16c61439c828df83","https://github.com/erlang/otp/releases/tag/OTP-25.3.2.21","https://github.com/erlang/otp/releases/tag/OTP-26.2.5.12","https://github.com/erlang/otp/releases/tag/OTP-27.3.4"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:27:07.145922Z"},"effective_severity":"LOW","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"N","value_label":"None"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"erlang","vendor_name":"erlang","product_slug":"otp","product_name":"OTP","version_start":">= OTP 27.0, < OTP 27.3.4","version_start_inclusive":true,"version_end":">= OTP 27.0, < OTP 27.3.4","version_end_inclusive":true,"cpe23_uri":"cve5:erlang:otp:>= OTP 27.0, < OTP 27.3.4:>= OTP 27.0, < OTP 27.3.4"},{"vendor_slug":"erlang","vendor_name":"erlang","product_slug":"otp","product_name":"OTP","version_start":">= OTP 26.2.1, < OTP 26.2.5.12","version_start_inclusive":true,"version_end":">= OTP 26.2.1, < OTP 26.2.5.12","version_end_inclusive":true,"cpe23_uri":"cve5:erlang:otp:>= OTP 26.2.1, < OTP 26.2.5.12:>= OTP 26.2.1, < OTP 26.2.5.12"},{"vendor_slug":"erlang","vendor_name":"erlang","product_slug":"otp","product_name":"OTP","version_start":"< OTP 25.3.2.21","version_start_inclusive":true,"version_end":"< OTP 25.3.2.21","version_end_inclusive":true,"cpe23_uri":"cve5:erlang:otp:< OTP 25.3.2.21:< OTP 25.3.2.21"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/erlang/otp/security/advisories/GHSA-934x-xq38-hhqf","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/erlang/otp/commit/e4b56a9f4a511aa9990dd86c16c61439c828df83","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/erlang/otp/releases/tag/OTP-25.3.2.21","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/erlang/otp/releases/tag/OTP-26.2.5.12","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/erlang/otp/releases/tag/OTP-27.3.4","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-05-08T19:26:27.563000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:46:37.370372Z","label":"CVSS score revised","source":"cvelistv5"}]}
