CVE-2021-24436 is a reflected Cross-Site Scripting (XSS) vulnerability in the W3 Total Cache WordPress plugin prior to version 2.1.4. An unescaped "extension" parameter in the Extensions dashboard allows attackers to inject malicious JavaScript. This medium-severity vulnerability (CVSS 6.1) requires user interaction, as an authenticated administrator must click a crafted link, potentially leading to full site compromise. While no active exploitation or public exploit code (Metasploit, ExploitDB) has been observed, a Nuclei template exists, and community discussion and media coverage are minimal.
