CVE-2026-114715
Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by an incorrect authorization vulnerability in the Modoboa driver of the password plugin. The driver took the first entry of the account search result returned by the Modoboa API instead of matching the authenticated user, so a password change could be applied to a different account. Upstream fixed this in the commit “Fix bug where Password Modoboa driver could change password for another account”, which selects the account whose username matches and fails if none does.
