Share This Image <= 2.03 - Open Redirect via link Parameter

The Share This Image plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 2.03. This is due to insufficient validation on the redirect url supplied via the link parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

The ILLID Share This Image plugin before 1.04 for WordPress has XSS via the sharer.php url parameter.
