EUVD-2026-110648
Severity: MEDIUM
Base Score: 6.3
CVSS Version: 4.0
Vulnerability Description
The twofactor_gauthenticator plugin for Roundcube is vulnerable to session persistence after failed 2FA verification. Due to the lack of server-side session destruction, an attacker can ignore the logout redirect and keep the session alive. This may allow an attacker who obtains user's password to e.g. brute force the second-factor code.
This issue was fixed in commit 4640889.
