Summary

The PowerPress plugin for WordPress is exposed to a serious Stored Cross-Site Scripting flaw due to inadequate input sanitization and output escaping for user-supplied attributes within its shortcodes. This vulnerability allows authenticated users with contributor-level permissions or higher to insert arbitrary web scripts into WordPress pages, which are executed when any user accesses these compromised pages.
