What the vulnerability does
The CryptX plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `cryptx` shortcode in all versions up to, and including, 4.0.5 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
CryptX versions up to 4.0.5 contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts. The vulnerability has a changed scope, meaning the impact can extend beyond the vulnerable component to affect other users or systems. Update to version 4.0.6 or later to remediate.
What an attacker can do
Inject and execute malicious JavaScript in the application, affecting other users or connected systems.
Potential impact on your site
Authenticated users can inject scripts that compromise other users' sessions, steal data, or deface content.
Conditions required to exploit
Attacker must have a valid user account with low-level privileges and network access to the application.
