{"id":"CVE-2026-114732","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-114732","summary":null,"details":"Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an improper authentication vulnerability in multi-host installations. 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":"2026-10-22T02:16:51.833Z","modified":"2026-10-31T02:30:44.031923065Z","cvss":{"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"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":{"url":"https://github.com/roundcube/roundcubemail/commit/453c413d6851cf603bebdb15e58381f5ef9b8094","label":"roundcube/roundcubemail@453c413"},"references":[{"type":"WEB","url":"https://github.com/roundcube/roundcubemail/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114732.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114732"},{"type":"ADVISORY","url":"https://roundcube.net/news/2026/10/19/security-updates-1.6.20-and-1.7.5"},{"type":"REPORT","url":"https://bugs.debian.org/1151279"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/453c413d6851cf603bebdb15e58381f5ef9b8094"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/cb235cbfef88cbf78236dc67d3b667bf3dc61ddd"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.6.20"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.7.5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-31T02:30:44.031923065Z"}}
