Description
The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.3.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
