Vulnerability Title
RSS Aggregator by Feedzy <= 5.2.13 - Unauthenticated Stored Cross-Site Scripting via Feed Item Title
Source: CVE Program / CVE List V5
Vulnerability 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 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.
