What is CVE-2026-18881?

The TableOn – WordPress Posts Table Filterable plugin is prone to a blind SQL Injection vulnerability which allows attackers to manipulate the SQL queries executed by the application. This issue arises from inadequate escaping of user-supplied data, particularly through the filter_data[comment_count] parameter in the tableon_get_table_data AJAX action. Without proper sanitization, unauthenticated attackers can append arbitrary SQL queries to the existing SQL, potentially extracting sensitive information such as usernames and passwords from the database.

Affected Version(s)

TableOn – WordPress Posts Table Filterable 0 <= 1.0.5.1
