Recommended action

Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Wazuh 4.0.0 至 4.14.9 之前的版本中，由于正则表达式占位符的连续交叉污染问题，WazuhDBBackend._substitute_params 组件存在 SQL 注入漏洞。拥有对某一代理（agent）"agent:read"权限的认证用户，可通过 q 和 search 参数注入 UNION SELECT 语句，并利用 total_affected_items 字段的盲注布尔预言机（blind boolean oracle）提取所有代理的内部密钥（internal_key）。
