## Description

The iChart plugin for WordPress is vulnerable to Insecure Direct Object Reference via the qcld_ichart_save_datasets AJAX action in all versions up to, and including, 2.2.3. This is due to missing validation that the current user can edit the post given in the user-controlled 'post_id' parameter. This makes it possible for authenticated attackers, with Subscriber-level access and above, to overwrite the chart datasets and colour codes stored in the post meta of arbitrary posts.
