W3 Total Cache <= 2.1.4 - Reflected Cross-Site Scripting via extension

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2021-24452
CVSS High (7.2)
Publicly Published June 28, 2021
Last Updated January 22, 2024
Description

The W3 Total Cache WordPress plugin before 2.1.5 was affected by a reflected Cross-Site Scripting (XSS) issue within the "extension" parameter in the Extensions dashboard, when the 'Anonymously track usage to improve product quality' setting is enabled, as the parameter is output in a JavaScript context without proper escaping. This could allow an attacker, who can convince an authenticated admin into clicking a link, to run malicious JavaScript within the user's web browser, which could lead to full site compromise.
