CVE-2023-4372 describes a Stored Cross-Site Scripting (XSS) vulnerability in the LiteSpeed Cache plugin for WordPress, affecting versions up to and including 5.6. Authenticated attackers with contributor-level permissions or higher can inject malicious web scripts through the 'esi' shortcode due to insufficient input sanitization. This medium-severity vulnerability (CVSS 5.4) allows for client-side script execution when a user accesses an affected page, potentially leading to information disclosure or session hijacking. While there is no evidence of active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB), the vulnerability has garnered some community discussion, with one Reddit mention incorrectly stating it as unauthenticated.
