What the vulnerability does
The Super Page Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Activity Log in all versions up to, and including, 5.2.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Super Page Cache versions 5.2.2 and earlier contain a cross-site scripting (XSS) vulnerability that allows attackers to inject malicious scripts into cached pages. The vulnerability affects all users viewing the site, as the injected code executes in their browsers without requiring authentication. This can lead to session hijacking, credential theft, or malware distribution.
What an attacker can do
Inject malicious JavaScript that executes in visitors' browsers and steals session cookies or credentials.
Potential impact on your site
Visitors' browsers execute attacker-controlled code, risking account compromise and data theft across your entire site.
Conditions required to exploit
Network access to the site; no authentication or user interaction required.
