The Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI plugin for WordPress is vulnerable to time-based SQL Injection via the "getTermsForAjax" function in all versions up to, and including, 3.40.1. This is due to insufficient escaping on the user supplied parameters and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with contributor level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database granted they have metabox access for the taxonomy (enabled by default for contributors).

The Tag, Category, and Taxonomy Manager – AI Autotagger with OpenAI plugin for WordPress is vulnerable to SQL Injection via the 'posttypes' parameter in all versions up to, and including, 3.40.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The WordPress Tag, Category, and Taxonomy Manager WordPress plugin before 3.30.0 does not sanitise and escape some of its Widgets settings, which could allow high privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfilteredhtml capability is disallowed (for example in multisite setup).
