Summary

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.

Risk Assessment

An authenticated attacker with low privileges can inject malicious scripts into WordPress pages that execute in visitors' browsers, potentially leading to session data theft or account takeover.

Recommendation

Update the CryptX plugin to a version later than 4.0.5 as soon as it is available; until then, consider restricting content publishing capabilities for low-privileged users.
