CVE-2025-50866 is a reflected cross-site scripting vulnerability in CloudClassroom-PHP-Project 1.0. The issue is present in the postquerypublic endpoint, specifically in handling of the email parameter. According to the provided information, the application does not properly sanitize or neutralize attacker-controlled input before reflecting it into a browser-consumed response. As a result, an attacker can supply crafted JavaScript payloads via the email parameter and cause that script to execute in the security context of a victim user's browser when the malicious request or link is processed.

This repository documents a proof-of-concept (POC) exploit for a reflected Cross-site Scripting (XSS) vulnerability in CloudClassroom-PHP-Project 1.0. The vulnerability exists in the 'postquerypublic.php' component, specifically in the 'email' parameter of POST requests. The exploit works by sending a crafted POST request to the '/CloudClassroom-PHP-Project-master/postquerypublic' endpoint, injecting malicious JavaScript via the 'email' parameter. The repository contains two files: a detailed exploit description and a README.md, both outlining the vulnerability, affected product, attack vector, and reproduction steps. The exploit demonstrates the ability to execute arbitrary JavaScript in the victim's browser, potentially leading to session hijacking or phishing. No actual exploit code is provided; instead, the repository gives a clear attack scenario and payload example for testing the vulnerability.
