## Technical details

A reflected cross-site scripting (XSS) vulnerability exists in the WordPress Jetpack plugin version 9.1. The flaw is located within the grunion-form-view.php endpoint, which fails to properly sanitize the 'post_id' parameter before rendering it in the browser. An unauthenticated remote attacker can exploit this by crafting a malicious URL containing a JavaScript payload. When a victim visits the link, the script executes within the context of their browser session, potentially allowing for session hijacking or unauthorized administrative actions if the victim is an authenticated site owner. A public proof-of-concept exploit has been disclosed.
