What is CVE-2023-2083?
The Essential Blocks plugin for WordPress has a security vulnerability that allows unauthorized users to alter plugin settings due to a lack of proper functionality checks. Specifically, a capability verification check is missing in the save function for configurations, enabling subscriber-level attackers to carry out changes without the necessary permissions. Although a nonce check is present, it only triggers when a nonce is provided. This oversight allows the nonce verification to be bypassed entirely if a nonce is not included, leading to potential exploitation of the plugin's settings.
