CVE-2026-74041— Wazuh 4.14.3 before 4.14.8 Remote Command Validation Bypass via Case Mismatch

Quick assessment

Affected
Wazuh wazuh-manager
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Wazuh 4.14.3 至 4.14.8 版本之间存在大小写敏感性问题，ossec.conf 验证器与 wazuh-logcollector 之间的不匹配可绕过远程命令验证。拥有 manager:update_config 权限的已认证用户可注入大写 LOG_FORMAT 命令的 localfile，在重新加载时该命令将以 root 权限在收集器上执行。
