Summary

The RSS Aggregator by Feedzy plugin for WordPress is affected in all versions up to and including 5.2.13. Feed item titles are stored without sufficient input sanitization or output escaping, a flaw classified as CWE-79. An unauthenticated attacker can inject scripts that run when a user opens an affected page, once an administrator has set up a Feed-to-Post import from an attacker-controlled feed.

Description from the CNA

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 the 'item_title (parsed from feed <item><title>)' parameter in all versions up to, and including, 5.2.13 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This requires an administrator to have previously configured a Feed-to-Post import pointing at an attacker-controlled feed URL, after which the attacker can rotate payloads at will without any further interaction with the site.
