## Description

The iChart plugin for WordPress is vulnerable to Sensitive Information Exposure via the qcld_ai_get_chart AJAX action in all versions up to, and including, 2.2.2. This is due to a missing capability check and no post-type restriction on the user-supplied 'post_id' parameter, with only a nonce check that was exposed to all logged-in users. This makes it possible for authenticated attackers, with Subscriber-level access and above, to read chart datasets, prompts and chart type metadata stored on arbitrary posts, including unpublished charts.
