Wordfence advisory
medium · CVSS 6.6The HTTP Headers plugin for WordPress is vulnerable to SQL Injection via the 'http_headers_post_import' and 'http_headers_post_export' functions in versions up to, and including, 1.18.8 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 administrator-level permissions to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Note that 1.18.8 provided a partial patch by restricting this capability to Super Administrators.
