Detailed vulnerability description
The vulnerability allows a remote user to access internal services via server-side request forgery.
The vulnerability exists due to improper restriction of outbound requests in isSelfRequest() when validating external hosts. A remote user can supply a crafted URL containing the server hostname in the path component to access internal services via server-side request forgery.
This issue is caused by substring matching with stripos() instead of hostname equality, which allows bypass of IP validation.
