W3 Total Cache <= 2.1.4 - Reflected Cross-Site Scripting via extension
| CVE | CVE-2021-24452 |
|---|---|
| CVSS | 7.2 (High) |
| 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.
