## Description

The PubPla AI Help Center plugin for WordPress is vulnerable to Sensitive Information Exposure via the saved AI conversations post type in all versions up to, and including, 2.6.0. This is due to a missing authorization restriction: the post type only overrode the 'create_posts' capability and otherwise used the default 'post' capabilities, so any user with 'edit_posts' could open its admin list. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the questions site visitors typed into the AI chat, which are stored as conversation titles and may contain personal information, on sites where saving conversations is turned on.
