{"schema":"threatline.record/2","record":{"id":"CVE-2026-23760","aliases":[],"summary":"SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel Vulnerability","details":"SmarterTools SmarterMail contains an authentication bypass using an alternate path or channel vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. This could allow an unauthenticated attacker to supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance.","categories":["Unclassified"],"product":"SmarterMail","vendor":"SmarterTools","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-23760","source_modified_at":"2026-08-04T03:56:03.047Z","fetched_at":"2026-10-23T18:42:43.628194Z","product":"SmarterMail","vendor":"SmarterTools","versions":[{"lessThan":"100.0.9511","status":"affected","version":"0","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-23760","source_modified_at":"2026-08-04T03:56:03.047Z","fetched_at":"2026-10-23T18:42:43.628194Z","package":{"name":"SmarterMail","ecosystem":null},"version":"100.0.9511","basis":"first unaffected version stated in the CVE record"}],"cvss":9.3,"severity":"Critical","kev":{"listed":true,"date_added":"2026-01-26","due_date":"2026-02-16","required_action":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.","ransomware_campaign_use":"Known"},"epss":{"probability":0.96432,"percentile":0.99883,"score_date":"2026-10-23"},"published_at":"2026-01-22T14:35:17.235Z","modified_at":"2026-08-04T03:56:03.047Z","provenance":[{"source":"CISA KEV","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23T17:00:09.9001Z"},{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-23760","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-08-04T03:56:03.047Z"},{"source":"Nuclei","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-23760.yaml","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":null},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-23760","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CISA KEV","CVE List","Nuclei","EPSS"],"references":[{"source":"CVE List","url":"https://www.smartertools.com/smartermail/release-notes/current","tags":["release-notes","patch"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-23760","source":"CISA KEV"},{"source":"CVE List","url":"https://labs.watchtowr.com/attackers-with-decompilers-strike-again-smartertools-smartermail-wt-2026-0001-auth-bypass/","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://code-white.com/public-vulnerability-list/#authenticationserviceforceresetpassword-missing-authentication-in-smartermail","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/smartertools-smartermail-authentication-bypass-via-password-reset-api","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://www.huntress.com/blog/smartermail-account-takeover-leading-to-rce","tags":["third-party-advisory"]},{"source":"CVE List","url":"https://www.cisa.gov/known-exploited-vulnerabilities-catalog?field_cve=CVE-2026-23760","tags":["government-resource"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"active","automatable":"yes","technical_impact":"total","assessed_at":"2026-01-22T00:00:00+00:00"},"exploits":[{"source":"Nuclei","kind":"Scanner template","name":"SmarterTools SmarterMail - Admin Password Reset","url":"https://github.com/projectdiscovery/nuclei-templates/blob/main/http/cves/2026/CVE-2026-23760.yaml"}],"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-08-04T03:56:03.047Z","content_hash":"ff70c31a5661a48173cd7325b92504dfe060d3865b6b516330e94c01cc913184"}}
