An attacker can supply malicious JavaScript in the postTitle value, which the application stores and later renders without proper encoding, enabling a stored cross\u2011site scripting attack.

However, the description indicates the exploit is available over the Internet and can be triggered remotely by delivering a crafted postTitle payload that is subsequently rendered in the browser.
