What the vulnerability does
The CM Registration – Tailored tool for seamless login and invitation-based registrations plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 2.5.6. This is due to insufficient validation on the redirect url supplied via the 'redirect_url' 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.
Explanation of Vulnerability in Simple Terms
CM Registration versions 2.5.6 and earlier contain an open redirect vulnerability. An attacker can craft a malicious link that redirects users to an external website after they interact with the registration or login flow. The vulnerability requires user interaction and does not directly compromise site data, but can be used in phishing attacks to steal credentials.
What an attacker can do
Redirect users to a malicious external website via a crafted link in the registration or login flow.
Potential impact on your site
Users may be redirected to phishing sites impersonating your login page, risking credential theft.
Conditions required to exploit
User must click a malicious link or visit a page containing the redirect.
