CVE-2026-107147 · Authentication bypass by spoofing in twofactor_gauthenticator
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
The twofactor_gauthenticator plugin for Roundcube is vulnerable to 2fa authentication bypass by spoofed client address headers. Due to the lack of validation of the Client-IP and X-Forwarded-For headers, an attacker who obtains user's password can spoof a whitelisted IP address, resulting in the second factor being bypassed. This issue was fixed in commit 4640889.
