CVE-2026-12492 Happy Coders CVE debrief

Who should care

Administrators and users of the Happy Coders OTP Login for WooCommerce WordPress plugin should be aware of this vulnerability and take immediate action to update to version 2.8 or later. This vulnerability has a high impact on the security of the affected systems, and defenders should prioritize remediation efforts. Security teams, vulnerability management teams, and operators of the affected plugin should review the vulnerability details and take necessary actions to protect their systems.

Technical summary

The Happy Coders OTP Login for WooCommerce WordPress plugin before 2.8 does not verify that a one-time password was actually validated before authenticating a user based on a supplied identifier. This allows unauthenticated attackers to log in as any existing user, including administrators, as well as to create new accounts. The plugin's authentication mechanism is flawed, allowing attackers to bypass security measures. Defenders should update to version 2.8 or later and monitor for suspicious activity.
