AI Puffer < 2.4.90 - Missing Authorization to Authenticated (Subscriber+) Global Plugin Settings Modification via ajax_save_cpt_indexing_options AJAX Endpoint

Description

The AI Puffer – Chat. Create. Automate. (formerly AI Power) plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.4.89. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify global plugin indexing and vector-search configuration options (aipkit_training_general_settings and aipkit_indexing_field_settings), including chunking parameters, file upload visibility, and per-CPT field indexing settings, affecting all users of the plugin. This is only exploitable in configurations where an administrator has granted 'sources' module access to a lower-privileged role via the plugin's Role Manager.
