Executive Summary

This vulnerability involves the access control settings for forum post custom fields in EasyDiscuss not being applied to the JSON output type. This means that the access control list (ACL) restrictions intended to protect certain data are bypassed when the data is output in JSON format, leading to unauthorized access to information.

Impact Analysis

The vulnerability can lead to an information disclosure where sensitive or restricted data from forum post custom fields may be exposed to unauthorized users. Since the ACL protections are not enforced on JSON outputs, attackers or unauthorized users could access data they should not have permission to see, potentially compromising privacy and security.
