The Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the taxopress_ai_add_post_term function in all versions up to, and including, 3.41.0. This makes it possible for authenticated attackers, with Contributor-level access and above, to add or remove taxonomy terms (tags, categories) on any post, including ones they do not own.
