When a user logs in with an alias address, rcube_user::query() matched the address against identity records without qualifying the lookup by IMAP host, so a login could be resolved to a user account belonging to a different IMAP host. Upstream fixed this in the commit “Fix bug where an alias login wasn’t qualified by IMAP host”.","published":"2026-10-22T03:16:39.000Z","lastModified":"2026-10-22T16:45:50.000Z","status":"Awaiting Analysis","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":6.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N"},"cwe":["CWE-288"],"affected":[],"epss":{"score":0.00359,"percentile":0.29448,"date":"2026-10-27","history":[{"date":"2026-10-22","score":0.00358,"percentile":0.28382}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.36%).
