CVE-2026-114715: Roundcube Webmail incorrect authorization in Modoboa password driver

CVE-2026-114715 · Severity: medium · CVSS 6.8 · Published 2026-10-22

Roundcube Webmail is a web-based email client used by organizations to access email. The password change feature in the Modoboa authentication driver fails to validate which account is being modified, allowing an attacker to change the password for a different user account. This could result in account takeover if an attacker changes another user's password.

Technical details

The Modoboa driver in the password plugin selects the first result from an account search API response instead of matching the authenticated username, causing a password change to be applied to an unintended account. The vulnerability requires authentication but no user interaction beyond a password change request. An attacker with valid credentials can modify another user's password by exploiting the first-match behavior of the API query.
