CVE-2023-2548: Metagauss Registrationmagic

High severity, CVSS 7.2. EPSS: 0.7% chance of exploitation in the next 30 days.

The RegistrationMagic plugin for WordPress is vulnerable to Insecure Direct Object References in versions up to, and including, 5.2.0.5. This is due to the plugin providing user-controlled access to objects, letting a user bypass authorization and access system resources. This makes it possible for authenticated attackers, with administrator-level permissions and above, to change user passwords and potentially take over super-administrator accounts in multisite setup.

Affected products

• Metagauss Registrationmagic: up to and including 5.2.0.5
