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.","published":"2026-09-30T21:16:57.000Z","lastModified":"2026-10-08T13:43:25.000Z","status":"Analyzed","sourceIdentifier":"9119a7d8-5eab-497f-8521-727c672e3725","cvss":{"version":"3.1","score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"},"cwe":["CWE-287"],"affected":["accellion/kiteworks"],"epss":{"score":0.01071,"percentile":0.64644,"date":"2026-10-26","history":[{"date":"2026-10-01","score":0.00636,"percentile":0.48557}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.07%).
