CVE-2024-47875 is a nesting-based mutation cross-site scripting (mXSS) vulnerability in DOMPurify, a DOM-based sanitizer for HTML, MathML, and SVG. Crafted nested markup can undergo browser DOM mutation after sanitization, causing active content to emerge despite DOMPurify sanitization. The flaw is fixed in DOMPurify 2.5.0 and 3.1.3.

This repository is a proof-of-concept (PoC) exploit for CVE-2024-47875 (also referenced as CVE-2025-22131), a Cross-Site Scripting (XSS) vulnerability in PhpSpreadsheet versions prior to 2.2.2, 2.1.2, and 1.29.4. The exploit leverages the generateNavigation() function's failure to sanitize sheet names during XLSX-to-HTML conversion, allowing an attacker to inject arbitrary JavaScript via a crafted XLSX file. The main file, 'exploit.py', is a Python script that automates the creation of malicious XLSX files with various XSS payloads (cookie theft, redirect, alert, keylogger, form hijack, data exfiltration, or custom JavaScript). It also includes a built-in HTTP server to receive callbacks from the victim's browser and can upload the malicious file to a specified endpoint on the target application. The README provides detailed usage instructions and describes the exploit's features. The repository is structured with a single exploit script, a README, and a license file. The exploit is operational as a PoC and demonstrates the impact of the vulnerability, but does not include weaponized or framework-level automation.
