 "title": "RSS Aggregator by Feedzy <= 5.2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via Loop Block",
 "description": "The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the Feedzy Loop block in versions 5.0.0 up to, and including, 5.2.10. This is due to the block inserting values from the fetched feed, such as the item title, link and content, into its template's magic tags without output escaping. This makes it possible for authenticated attackers with contributor-level access and above to point the block at a feed they control and inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.",
