Loading vulnerability…
The Simple URLs WordPress plugin before version 115 fails to properly sanitize and escape certain parameters before reflecting them in output on some pages. This allows an attacker to craft a URL containing malicious JavaScript, which, when visited by a user with high privileges (such as an admin), results in the execution of arbitrary scripts in the context of the victim's session. The vulnerability is a classic reflected cross-site scripting (XSS) issue.

This repository contains an exploit for CVE-2023-0099, a reflected XSS vulnerability in the Simple URLs WordPress plugin (versions < 115). The exploit consists of a single JavaScript file (exploit.js) and a detailed README.md. The JavaScript payload, when executed in the context of an authenticated admin user (typically via a crafted malicious link), retrieves a CSRF token and submits a POST request to create a new administrator account on the vulnerable WordPress site. The README provides usage instructions, including how to modify the payload and how to deliver the exploit via a reflected XSS vector. The exploit targets WordPress installations running the vulnerable plugin and leverages browser-based attack vectors. The repository is straightforward, with clear separation between documentation and exploit code.
