What is CVE-2024-8243?

The Upgrade Time Out Plugin for WordPress prior to version 1.0 is vulnerable to a stored Cross-Site Scripting (XSS) attack due to insufficient CSRF checks and a lack of proper sanitization and escaping of input. This weakness enables attackers to exploit the plugin's functionality, potentially allowing logged-in administrators to unknowingly add malicious scripts. The resulting XSS payloads could be executed in the context of website users, compromising their security and privacy.
