{"schema":"threatline.record/2","record":{"id":"CVE-2026-100718","aliases":["GHSA-m9j6-9856-68xf"],"summary":"Froxlor before 2.3.12 Authentication Bypass via EmailSender.add","details":"Froxlor through 2.3.10 does not enforce the mail.allow_external_domains policy in the EmailSender.add API command. When an administrator has enabled the allowed-sender feature but disabled external allowed-sender domains (mail.enable_allow_sender = 1, mail.allow_external_domains = 0), an authenticated customer with API access can still use EmailSender.add to register an arbitrary external sender address for their mailbox, which is stored despite the policy. This creates a bypass between the UI/administrator configuration and the API, and — where the generated mail configuration consumes the allowed-sender table — allows a customer to authorize sender identities outside their hosted domains, facilitating sender spoofing. Fixed in 2.3.12.","categories":["Unclassified"],"product":"froxlor","vendor":"froxlor","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100718","source_modified_at":"2026-09-26T23:07:02.407Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"froxlor","vendor":"froxlor","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"2.3.12"},{"version":"2.3.12","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-100718","source_modified_at":"2026-09-26T23:07:02.407Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"name":"froxlor","ecosystem":null},"version":"2.3.12","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00186,"percentile":0.07807,"score_date":"2026-10-23"},"published_at":"2026-09-26T13:24:09.189Z","modified_at":"2026-09-26T23:07:02.407Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-100718","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-26T23:07:02.407Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-100718","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/froxlor/froxlor/security/advisories/GHSA-m9j6-9856-68xf","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/froxlor-before-2.3.12-authentication-bypass-via-emailsender-add","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":"no","technical_impact":"partial","assessed_at":"2026-09-26T23:06:54.103708Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-26T23:07:02.407Z","content_hash":"173b6dc54732381e9b15ff1be4e41468c25e2025c14235b411ad259946923ec8"}}
