CVE-2024-9442

Summary

The F4 Improvements plugin for WordPress is susceptible to Stored Cross-Site Scripting (XSS) through SVG file uploads, affecting all versions up to and including 1.9.0.

These scripts execute whenever a user accesses the compromised SVG file, potentially leading to unauthorized actions or information disclosure.
