Details

The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.1.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to create and execute RSS import jobs, purge (force-delete) all posts associated with any import job, clear import error logs, and enumerate taxonomy terms and post meta_key names. The nonce required to reach these sub-handlers is leaked to any user with the edit_posts capability via the feedzyjs localized script injected into the block editor, meaning no privileged nonce theft or separate exploit step is required for Contributor-level users.

Severity
4.3 (Medium)
