## Technical details

The Feedzy RSS Aggregator plugin for WordPress (versions up to 5.1.7) fails to implement proper capability checks on several administrative sub-handlers within the feedzy-rss-feeds-import.php file. While these actions are protected by nonces, the required nonce is leaked to any user with 'edit_posts' capabilities via the 'feedzyjs' localized script in the block editor. This combination allows authenticated attackers with Contributor-level permissions or higher to bypass intended authorization. Exploitation enables attackers to create/execute RSS import jobs, force-delete posts associated with any import job, clear error logs, and enumerate taxonomy terms or post meta keys.
