Name of the Vulnerable Software and Affected Versions Defender Security plugin for WordPress versions up to, and including, 2.4.6

Description The issue is related to Cross-Site Request Forgery due to missing or incorrect nonce validation on the verify otp login time() function. This allows unauthenticated attackers to verify a one-time login via a forged request if they can trick a site administrator into performing an action, such as clicking on a link.

Recommendations For versions up to, and including, 2.4.6, update to a version that includes the fix for the missing or incorrect nonce validation in the verify otp login time() function. As a temporary workaround, consider restricting access to the verify otp login time() function until a patch is available.
