CVE-2026-107146
The twofactor_gauthenticator plugin for Roundcube is vulnerable to session persistence after failed 2FA verification.
Impact
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.
