Essential Blocks <= 4.0.6 - Missing Authorization via templates

Missing Authorization
CVE CVE-2023-2085
CVSS Medium (4.3)
Publicly Published April 18, 2023
Last Updated January 22, 2024
Researcher Marco Wotschka
Description

The Essential Blocks plugin for WordPress is vulnerable to unauthorized use of functionality due to a missing capability check on the templates function in versions up to, and including, 4.0.6. This makes it possible for subscriber-level attackers to obtain plugin template information. While a nonce check is present, it is only executed when a nonce is provided. Not providing a nonce results in the nonce verification to be skipped. There is no capability check.
