Summary

The WP Custom HTML Page WordPress plugin through version 0.6.2 does not sanitize HTML stored through one of its custom page handlers, nor restrict it to users allowed to post unfiltered HTML. Users with the Author role can store JavaScript that is served unescaped at a public URL and executes for any visitor, including administrators.

Risk Assessment

An attacker with Author role can execute malicious scripts in an administrator's browser, potentially leading to session hijacking, data theft, or other harmful actions in the admin context.

Recommendation

Update the plugin to the latest version if a patch is available. Restrict user roles and implement a Content Security Policy (CSP) to minimize the risk of script execution.
