Mon projet comporte 6 vulnérabilités de gravité élevée et je ne sais pas comment les corriger. Le correctif d'audit npm échoue. Veuillez m'aider à résoudre ce problème.
J'installais https://www.npmjs.com/package/toastr sur mon projet et après l'installation, les vulnérabilités ont été affichées. Je ne sais pas s'il y a un lien. === npm rapport de sécurité d'audit ===
