Missing Authorization
CVE CVE-2023-2085
CVSS 4.3 (Medium)
Publicly Published April 18, 2023
Last Updated June 9, 2023
Researcher Marco Wotschka - Wordfence

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.
