What is CVE-2026-94112?

The mayswind ezBookkeeping application, prior to version 2.0.0, contains a vulnerability wherein Time-based One-Time Password (TOTP) passcodes are not invalidated after their initial use. This oversight enables attackers to replay intercepted codes within a 90-second window, facilitating unauthorized access. An attacker equipped with stolen credentials can authenticate multiple authorization attempts using a captured passcode without detection, posing significant security risks to user accounts.
