Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI <= 3.40.1 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Taxonomy Term Manipulation

The Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.40.1. This is due to the plugin not properly verifying that a user is authorized to perform an action in the "taxopress_merge_terms_batch" function. This makes it possible for authenticated attackers, with subscriber level access and above, to merge or delete arbitrary taxonomy terms.
