Technical details

The vulnerability is an Insecure Direct Object Reference (IDOR) in the front-end submission handling of the RegistrationMagic plugin. The root cause is a failure to properly validate that a one-time password (OTP) provided in a cookie matches the identity (email) being requested. An unauthenticated attacker can generate a valid OTP for their own email address and then use that OTP in conjunction with a victim's email address in the 'rm_autorized_email' cookie to access the victim's form submissions. This allows for the disclosure of PII collected via [RM_Front_Submissions] and [RM_Login] shortcodes. The issue is fixed in version 6.0.9.4.
