CVE-2023-2085 : What You Need to Know

This CVE-2023-2085 article provides insights into a vulnerability identified in the Essential Blocks plugin for WordPress, impacting versions up to and including 4.0.6. The vulnerability allows unauthorized access to plugin template information, posing risks for subscriber-level attackers.

Understanding CVE-2023-2085

This section delves into the details surrounding CVE-2023-2085, shedding light on its nature and impact.

What is CVE-2023-2085?

The Essential Blocks plugin for WordPress is susceptible to unauthorized usage of functionality due to a missing capability check within the templates function. In versions up to 4.0.6, this vulnerability enables attackers at the subscriber level to acquire plugin template information. Although a nonce check exists, it is only triggered when a nonce is provided; failure to do so bypasses the nonce verification process, revealing a lapse in capability checks.

The Impact of CVE-2023-2085

The potential exploitation of this vulnerability could lead to unauthorized disclosure of sensitive plugin template data, facilitating malicious activities by unauthorized users. The absence of a comprehensive capability check mechanism exposes the plugin to security risks, necessitating immediate mitigation measures.

Technical Details of CVE-2023-2085
