CVE-2021-26644Network attack vector

Data disclosure and code execution via table name

Published Jan 20, 2023 · Updated Apr 3, 2025

SQL injection in Hometory MangBoard WP BASIC 2.0.3 and earlier allows remote attackers to disclose data through an unvalidated table name. The bulletin-board database path accepts a table-name input without validation and incorporates it into an SQL operation. Exploitation requires a general user account and prior XSS-based administrator takeover; successful injection can expose data and execute server code.
