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”.","state":0,"publishedAt":"2026-10-22T02:16:51.833+00:00","modifiedAt":"2026-10-29T10:57:39.353+00:00","affected":[{"ecosystem":"Vendor product","name":"Webmail","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Webmail\",\n                    \"repo\": \"https://github.com/roundcube/roundcubemail/\",\n                    \"vendor\": \"Roundcube\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"1.6.20\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.6.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"1.7.5\",\n                            \"status\": \"affected\",\n                            \"version\": \"1.7.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N","score":6.8,"severity":"MEDIUM"}],"references":["https://bugs.debian.org/1151279","https://github.com/roundcube/roundcubemail/commit/453c413d6851cf603bebdb15e58381f5ef9b8094","https://roundcube.net/news/2026/10/19/security-updates-1.6.20-and-1.7.5","https://github.com/roundcube/roundcubemail/releases/tag/1.7.5","https://github.com/roundcube/roundcubemail/releases/tag/1.6.20","https://github.com/roundcube/roundcubemail/commit/cb235cbfef88cbf78236dc67d3b667bf3dc61ddd"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-114732","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-114732","identifiers":["CVE-2026-114732"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
