4.3
Missing Authorization
CVE CVE-2025-13354
CVSS 4.3 (Medium)
Publicly Published December 3, 2025
Last Updated December 3, 2025
Researcher type5afe

Description

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.
