essentialpluginEssential Chat Support
Description#
The Essential Chat Support plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.0.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to reset all plugin configuration settings — including general settings, display rules, custom CSS, and WooCommerce tab settings — to their defaults by sending a POST request with ecs_reset_settings=1.
Impact#
Per CVSS v3.1: confidentiality impact none, integrity impact low, availability impact none. Attack vector: network.
