{"id":"CVE-2026-23760","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-23760","generatedAt":"2026-10-31T05:59:15.488Z","title":"SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel Vulnerability","description":"SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass 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. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance. NOTE: SmarterMail system administrator privileges grant the ability to execute operating system commands via built-in management functionality, effectively providing administrative (SYSTEM or root) access on the underlying host.","published":"2026-01-22T15:16:55.000Z","lastModified":"2026-08-04T05:16:38.000Z","status":"Analyzed","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":9.3,"severity":"CRITICAL","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-288"],"affected":["smartertools/smartermail"],"epss":{"score":0.96432,"percentile":0.99881,"date":"2026-10-30","history":[]},"kev":{"listed":true,"dateAdded":"2026-01-26","dueDate":"2026-02-16","knownRansomwareCampaignUse":"Known","notes":"Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.\nhttps://www.smartertools.com/smartermail/release-notes/current ; https://nvd.nist.gov/vuln/detail/CVE-2026-23760"},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"Known to be exploited in the wild (CISA KEV, CISA remediation deadline 16 February 2026).
