CVE-2026-114732 is fixed in 2 products on 1 platform, first by DEBIAN-CVE-2026-114732, released October 24, 2026. It is not reported as exploited. Patch Radar priority: High.
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”.
