Database reads and writes via unescaped ordering parameter
Published Dec 13, 2021 · Updated Aug 3, 2024
SQL injection in CleverPlugins SEO Booster before 3.8 allows remote authenticated users to read and alter database data through an AJAX request. The fn_my_ajaxified_dataloader_ajax handler places the unescaped order[0][dir] request value into an SQL ordering clause, enabling blind and error-based queries. Administrator-level WordPress access is required, bounding exposure to users who can access the plugin's administrative interface.
