A flaw was found in Wordpress 5.1. "X-Forwarded-For" is a HTTP header used to carry the client's original IP address. However, because these headers may very well be added by the client to the requests, if the systems/devices use IP addresses which decelerate at X-Forwarded-For header instead of original IP, various issues may be faced. If the data originating from these fields is trusted by the application developers and processed, any authorization checks originating IP address logging could be manipulated.
建议您更新当前系统或软件至最新版,完成漏洞的修复。
