 "title": "RSS Aggregator by Feedzy <= 5.2.11 - Authenticated (Author+) Stored Cross-Site Scripting via Import Error Messages",
 "description": "The RSS Aggregator by Feedzy plugin for WordPress is vulnerable to Stored Cross-Site Scripting via import error messages in all versions up to, and including, 5.2.11, due to insufficient output escaping of stored import errors on the Imports list. Error messages can contain values taken from the fetched feed, such as item image URLs, which the plugin entity-decodes and stores without sanitization. This makes it possible for authenticated attackers with author-level access and above, who can create import jobs, to point an import at a feed they control and inject arbitrary web scripts that execute whenever a user, including an administrator, views the Imports list.",
