An administrative service in Kiteworks Email Protection Gateway did not consistently enforce administrator authentication, so the required password check could be bypassed. An attacker who referenced a valid administrator account could potentially create, modify, or delete internal users and managed domains and change their security-feature configuration without authenticating; deleting a managed domain also removes its user accounts and could lock administrators out of the gateway.","categories":["Network & edge"],"product":"Email Protection Gateway","vendor":"Kiteworks","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102106","source_modified_at":"2026-10-01T13:37:01.070Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Email Protection Gateway","vendor":"Kiteworks","versions":[{"lessThan":"9.5.0","status":"affected","version":"0","versionType":"custom"},{"status":"unaffected","version":"9.5.0"}],"defaultStatus":"unknown"},{"source":"GitHub Advisory Database","source_url":"https://github.com/kiteworks/security-advisories/security/advisories/GHSA-wwv8-qhqg-4q76","source_modified_at":"2026-10-02T03:40:01Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"other","name":"Kiteworks Email Protection Gateway"},"range":"< 9.5.0"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-102106","source_modified_at":"2026-10-01T13:37:01.070Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"Email Protection Gateway","ecosystem":null},"version":"9.5.0","basis":"first unaffected version stated in the CVE record"},{"source":"GitHub Advisory Database","source_url":"https://github.com/kiteworks/security-advisories/security/advisories/GHSA-wwv8-qhqg-4q76","source_modified_at":"2026-10-02T03:40:01Z","fetched_at":"2026-10-23T19:58:35.668311Z","package":{"ecosystem":"other","name":"Kiteworks Email Protection Gateway"},"version":"9.5.0"}],"cvss":9.1,"severity":"Critical","kev":{"listed":false},"epss":{"probability":0.01071,"percentile":0.64613,"score_date":"2026-10-23"},"published_at":"2026-09-30T20:24:46.723Z","modified_at":"2026-10-02T03:40:01Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-102106","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-01T13:37:01.070Z"},{"source":"GitHub Advisory Database","url":"https://github.com/kiteworks/security-advisories/security/advisories/GHSA-wwv8-qhqg-4q76","fetched_at":"2026-10-23T19:58:35.668311Z","source_modified_at":"2026-10-02T03:40:01Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-102106","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/kiteworks/security-advisories/security/advisories/GHSA-wwv8-qhqg-4q76","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://raw.githubusercontent.com/cisagov/CSAF/develop/csaf_files/VA/white/2026/va-26-274-01.json","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"yes","technical_impact":"partial","assessed_at":"2026-10-01T13:14:06.115234Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-02T03:40:01Z","content_hash":"ca055a19d19408ec64c1200ef7da62142bd89c137a650dfa2b286a24c9b94e07"}}
