Pour résoudre le problème, vous pouvez:
  * [[wordpress:bloquer_brute_force|Bloquer l'accès au fichier xmlrpc.php à l'aide d'un fichier .htaccess]]. IMPORTANT DE RENVOYER LA REQUÊTE VERS UN AUTRE SITE QUI N'EST PAS SUR VOTRE SERVEUR...EX: google.com.
  * Bloquer l'adresse IP (54.36.38.246 dans notre example) avec le firewall du serveur.

Il est aussi possible de bloquer les adresses IPs utilisés par Semrush via le Firewall. Parcontre, Semrush utilise une grande quantité d'adresses IPs. Comme dans notre exemple, plusieurs adresses IPs 46.229.168.XXX

Idéalement, vous pouvez bannir les plage entière de IPs pour régler le problème.
