CVE-2021-4363 – WP Quick FrontEnd Editor <= 5.5 - Reflected Cross-Site Scripting

https://notcve.org/view.php?id=CVE-2021-4363

The WP Quick FrontEnd Editor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting in versions up to, and including, 5.5 due to insufficient input sanitization and output escaping on the 'save_content_front' function that uses print_r on the user-supplied $_REQUEST values . This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. • https://blog.nintechnet.com/multiple-vulnerabilities-in-wordpress-wp-quick-frontend-editor-plugin-unpatched https://wordpress.org/plugins/wp-quick-front-end-editor/#developers https://www.wordfence.com/threat-intel/vulnerabilities/id/7ce8ae7d-c2a5-4da3-8bdd-20dfdb5ce700?source=cve • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
