Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.
You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.
What is this endpoint?
+target=/_blank
Opens the linked document in a new window or tab
What an attacker could do
Not a sensitive resource - this is an HTML attribute fragment that scanners append to URLs to test reflected XSS or tabnabbing where target=_blank without rel=noopener lets the new tab control the opener window.
How to defend it
Ensure all outbound links using target=_blank include rel="noopener noreferrer", and return a clean 404 for malformed paths without echoing input or leaking server version.
